Mark's GT-R Build

As I progress through the wiring, the instructions are great. Step by step process. The fob based wireless battery disconnect is facilitated by the solenoid in the first picture. Since so many systems suggest a direct battery connection, RFW provides a multiple positive terminal for those connections.

While I am working on the wiring, I take a few breaks to work on other things at the same time. You might recall that I wanted my rear grills to have a 3D look to them, which worked out great. After the body is painted, I want to be able to add the accessories, such as these grills, with minimal effort and no damage to the paintwork. To mount the grills, I epoxied screws to the fiberglass inside the vent openings and cut openings in the grills for these screws. I then modified brake line clamps by over bending them, to "Clamp" the grills in place.

Double check the rating on your solenoid to make sure it is rated for continuous duty. Many similar solenoids are made in two types- an intermittent- duty and a continuous-duty. An intermittent-duty solenoid will get too hot if energized for a long time.

Nice grill work!

Thanks Neil:
I checked with Ron Francis Wiring and it looks like they anticipated the loads and built the solenoid to match. Thanks for the heads up.

I am using the Summit Raptor Pro for wireless switching from the steering wheel and the output from their switches requires relays for everything. To achieve that, I made a relay panel to be mounted under the driver seat so as not to use up all of the circuits on the Ron Francis Programmable Relay Unit. My relay panel will have the incoming trigger wires coming in from the Raptor Pro to the circuit block on the lower left, with comparable "inside" wires going the relay. The right side will have the wires coming from the relay going to the circuit block, then out to the main fuse panel, then on to their end use. The center circuit block provides distribution of battery feed to the relays. Looks like a mess now, but hopefully it will be clean looking when I am done with it.

I started out not knowing much about auto wiring, but this technique of wiring a car is teaching me a ton, plus I get a chance to try to make it look good at the same time.

Typically when I build a relay pan like that I have 4 bus bars, the last one would be for ground. How are you going to ground all the relays?
I plan to run a continuous ground from one relay to the next, with a relay connector on each end of a short wire, then run the end relay to ground with one wire. I don't know if that is correct, but it can make things look nice. Let me know if that will create a problem. I saw it somewhere and it looked like a good idea. I will show a photo when I have things more complete.
Mark what was your biggest draw back of the Infinety System not being able to Taylor the wiring harness. Mark from what I am hearing the wiring harness is back ordered anyway maybe I will tell Fran to discount it out of my package Mark I have had great success using American Wiring Harness Kits very simple to install and come with all wires I.d and a wiring schematic anyone else out their use American Wiring
Hi Larry:
My experience may be different than others in that I am not using the GM Performance Engine Management System. I am also not using the steering wheel switching that comes with the GM steering column. I am using the Holley Dominator EFI system for engine management and using the Summit Raptor Pro wireless steering wheel switches. As a result, I was having to significantly modify the Infinity System. I was almost done wiring it, but I did not like the looks of it because the harness had some excess wire that I was having to loop and tuck away. Someone with more experience could cut and splice to make it look better. I am not finding fault with the Infinity System. It was really well made and a quality piece. I just wanted a system that I could understand when it was done, so that if there was a problem, I could fix it and I wanted it to end up looking great. I am not familiar with American Wiring. I just spoke with a lot of car builders on the Hot Rod Power Tour, and they all spoke highly of Ron Francis Wiring. Also, Ron McCall, on this forum, had me turn to them for my dual fan control module, and it went in great. I am a novice, and the Ron Francis system is going in great, and I understand exactly what I am doing.

It really depends on the loads you will be running. I'm not sure what the buttons on the steering wheel will be hooked up to, but each relay can handle 40 amps, which means you could theoretically be running 240 amps through a single 12-gauge ground wire. If your total amps for all relays combined are under 40, you should be okay. If you might top 40 amps, then consider a grounding bar with a 4-guage coming into and connecting each relay to the ground bar.


Mark, if it is the low current(coil) part of the relay you will ground in a continous loop, it’s totally OK.
The coil draws less than 1amp in most auto relays.
If it is the high current part, it is definetly not adviceable to run a continous ground, same goes for if you’re controlling 12V + , high current part should always have individual feed.
Thanks for your input. I have the Relay Panel wired as shown. I have yet to attach to the "input side" or the "output" side, but I will look at the amperage as I add to this. I have an entirely separate relay system from Ron Francis that I can use if things look to get overloaded. The one circuit I have set up is the starter button from the Summit Raptor Pro going to a relay, then going thru the fuse box, then to the starter solenoid. This use should be minimal in amps on the relay panel.

Shrink tubing on the crimp-on terminals-- a nice detail. Excellent wiring, Mark.

After writing the last entry yesterday. I realized that I did not solder the crimped connections that were provided in the pre-made components. so today I went through and soldered the connections that were crimped only from the manufacturer. The wiring order of business calls for the turn signal indicators and the high beam indicator to get wired next, but I had not installed them, so I spent some time finishing the dashboard layout, in preparation for it getting wired.

The wiring continues. I should have it wrapped up in a day or so. I don't want to show you any photos until I tidy things up. It can look a little messy when you are in the middle of a car wiring project.
Looking forward to getting back in my shop. I had a retinal tear and lost sight in one eye. Now the sight has returned enough to get back in the game. It happens out of nowhere.
