Celebrating 17 Years in Business: A Look Back at Nick’s Factory Five Hot Rod Build

We’re approaching 17 years in business, and it’s amazing how time flies! Over the years, we’ve helped countless enthusiasts bring their dream cars to life. Each build is special, but some really stand out as favorites.

Last week, we got a call from Nick S. He needed a little technical support for the Infinitybox system he purchased back in 2013 to wire his Factory Five Hot Rod. It was great catching up with him, hearing stories about his car, and knowing we played a part in making his dream build a reality. That inspired us to pull this project from the archives for a quick review—a true blast from the past. Thinking about wiring your Factory Five Hot Rod? See how Infinitybox can simplify the job.

Nick’s Dream Build

When Nick started planning his Hot Rod, he wanted the best. He chose a Ford 302 built by Norm Wilson of Fortin’s Engines, paired with a Ford AOD transmission from Performance Automatics. For the exhaust, he went with Magnaflow.

Inside, he upgraded from stock gauges to a Dakota Digital VHX-1017 cluster and built a beautiful custom console with wood-grain panels and a custom switch panel. The level of detail in this car is remarkable.

When it came to wiring, Nick also wanted the best. He chose our Infinitybox system to power his build. He wired the core functions of the car with our 20-Circuit Kit (the predecessor to today’s Next Generation IMP1 Kit) and added inLINK for wireless control.

He didn’t stop there—Nick also installed inMOTION to control his power windows. We even customized his programming to let his inLINK key fobs control door poppers and other accessories.

Step-by-Step Build Documentation

Nick went the extra mile by documenting his entire build on his personal website. He included step-by-step instructions, pictures, videos, and detailed sketches showing exactly how he wired the car with the Infinitybox system. It’s an incredible resource for anyone planning their own Factory Five or hot rod build. Check out Nick’s website here.

Standing the Test of Time

Nick received his Infinitybox system back in July 2013. More than a decade later, the system continues to perform reliably in his Hot Rod. We’ve been there to answer questions along the way, and we’re proud that our products stand the test of time.

August 24, 2018/in Cars /by admin

In 2008, we started selling our Infinitybox systems. We found our first success with guys building Factory Five Cobras. These guys are tinkers. They want something that they built, not bought. They want their cars to be different and unique. Our Infinitybox system has been instrumental for hundreds of Factory Five Roadsters, Hot Rods, GTM’s and 818’s. With our system, guys can simplify their electrical system plus get features that no other system can provide. We received these great pictures from Infinitybox customer Dan M. He’s just finishing his Cobra build and is very proud of the results.

He squeezed the Ford Coyote 5.0 under the hood. Check out how clean the engine compartment is.

He wired the system with our standard 20-Circuit Kit. This universal system is powering all of the electrical functions in the car including the ignition, starter, head lights, high-beams, turn signals, brake lights, fuel pump, horn and cooling fan. He integrated our system to the Ford ECU for the Coyote to simplify control of the ignition, starter solenoid, cooling fan and fuel pump. You can download the Infinitybox wiring diagram that shows how to connect to the Coyote harness by clicking this link.

Dan added inLINK as an option to his kit to get our security functions. Since this is an open top car, he wanted to do everything that could to prevent theft. Since his 20-Circuit Kit is controlling the ignition, fuel pump and starter, the security functions built into the Infinitybox system completely immobilize the car when he locks it from the inLINK key fobs. If a would-be thief were to try to hot wire the car, the Infinitybox system eliminates the ability to start the engine unless it is unlocked from the inLINK key fob.

Lastly, Dan added our inRESERVE battery management solenoid to his kit. inRESERVE is an active battery management system that disconnects the battery if the voltage starts to drop. This helps to reduce damage to the battery from deep-cycling and always leaves enough power in the battery to start the car.

This picture shows the rear POWERCELL mounted on the frame of the car. It also shows some of the included harnesses, the primary fuses included in the kit to protect the power harnesses and the inRESERVE solenoid.

This picture shows how neatly Dan did up his trunk to hide the rear POWERCELL. You can’t see any of the wiring but the system is also accessible in case you need to access the fuses.

We wanted to end this blog post with a quote from Dan. He sent us an email with these great pictures and these comments about our Infinitybox system.

“I can’t thank you enough for the help you gave me and the system your company produces. I am planning on post pictures and a write up on the Factory Five Forum over the weekend. I will be telling other builders that if you are worried about wiring you car then Infinitybox is for you, it makes a complicated part of the build much easier to understand and complete. Thank you for a wonderful product.”

Thank you to Dan W. for sharing these pictures and the comments about our system. We appreciate this and are proud to be a part of your car.

GTM410 Update

July 6, 2017/in Cars /by admin

We’re always getting progress updates from our customers who are wiring their cars with our Infinitybox system. We just got an update from John M. about his progress on his Factory Five GTM. We posted last year about this car before he took it apart to paint the body. You can see that post at this link. John did the paint on the body and the results are stunning. Check out the results.

John has our full system in his GTM. He’s using our 20-Circuit Kit as the electrical foundation. This is powering his lights, ignition, ECU, fans, fuel pump and other electrical accessories. He added inMOTION to control his power windows and power locks. He added inRESERVE to protect his battery from draining. Lastly, he added our inTOUCH NET so that he could control everything in the car from his phone or his head unit mounted in the dash.

John is buttoning up the last details on the car. He thinks that he’s a few months away from completing everything and getting the car on the road.

Updated 818 Manual

April 6, 2017/in Wiring /by admin

Guys have been wiring their Factory Five cars since we started this business over 8 years ago. Hundreds of our kits have been used in the MK4 Roadster, the ’33 Hot Rod, the Type 65 Coupe and the GTM Supercar. When Factory Five developed their new 818 a few years ago, we worked with their beta builders to create a configuration of our 20-Circuit Kit to help guys wire this car too. In addition to a configuration specific to this car, we created a detailed set of instructions showing you how to wire all of the Subaru switches directly to our MASTERCELL inputs. We just released an updated 818 manual based on recent customer feedback.

The original configuration for the 818 was set up exclusively for 1-filament brake lights. This means that the turn signal bulbs in the rear of the car worked together as the brake lights. When you flipped on the left turn signal, the output for the left turn signal would flash. Same for the right. If you stepped on the brake pedal, both the left and right turn signals on the rear POWERCELL would come on together for the brake lights. If you have a turn signal on when you stepped on the brake pedal, that turn signal would override the brake lights on that side of the car. The configuration was set up to match the tail lights that customers got in their kits from Factory Five.

Guys have wanted more flexibility with the tail lights that they were using on the back of the 818. In some cases, they were using clusters that had separate bulbs for the brake lights. We call this multi-filament turn signals. With this update, there is a dedicated brake light output on the rear POWERCELL that can be used for these light clusters. You simply pick a different input to the MASTERCELL for the brake pedal switch. All of this is detailed in the updated 818 manual.

If you want to learn more about the differences between single and multi-filament turn signals, you can read this blog post.

You can download the updated 818 manual by clicking this link.

We also update the configuration sheets for the 818 kit. There are two versions: you can download the standard version by clicking here or you can download the version set up for the optional inRESERVE solenoid by clicking here.

We received a great set of progress pictures from Infinitybox customer John. He is building a Factory Five Racing GTM and is wiring it with our Infinitybox system.

John is using our 20-Circuit Kit to power the main functions in the car. He also added inTOUCH NET so that he can control the car from a tablet mounted in the dash and from his smart phone.

John’s website has a lot of great pictures documenting the build of the car. This includes lots of good information on how he wired it with our Infinitybox system. Here’s a great picture of the MASTERCELL and the front POWERCELL located in the car.

The front POWERCELL is controlling the headlights, high-beams, front turn-signals, front running lights, horn, dash power and cooling fans. You can see how close these loads are located to the front POWERCELL. This will keep the total amount of wire needed to a minimum.

His rear POWERCELL is mounted just forward of the engine, at the back of the arm-rest. You can see it here.

This rear POWERCELL is controlling the power to the LS7 ECU, the starter solenoid, the fuel pump and all of the lights in the back of the car. Again, our multiplexing technology lets John eliminate a lot of the wire required in this car.

Thanks for John for sharing these pictures.
