First off I did about 75% of the hard wiring, which included the fly by wire gas pedal, MSD window switch for the control of the A/C compressor, starter, oil pressure, water temp, and more. However to energize some of these accessories it takes a "trigger" from the alternator or sensors that says the engine is turning, i.e. the Porsche fuel pump. There wasn't anyway that I could figure this part out, plus I didn't want to cobble up the wiring, I hate that... I took it one step further and we removed all of the non-essential wiring from the 2 engine room Canon plugs. Renegade just wads the whole mess up and hides it behind the rear seats. They have their reasons which I'm sure is because you can do away with needed wires later. However we left pig tails so if that happen we could go back and tie it in.
I finally hired a guy who really knew his way around these issues, he even made his own wiring loom, it looks just like factory. He also redid the oil level sensor so that still works. However we got down to a half of dozen electrical issues that were going to take some time to sort out so I put my guy back on the airplane and sent him home before I went broke.
Here's the issues right now. Some are just nagging issues, others are critical to the use of the car.
1. Water temp gauge trips which is all Porsche, but for some reason the ECU gets some inputs that it doesn't like and the pointer goes to zero. I can clear it with my Durametric software and it might go again for 100 miles before doing it again.
2. Even though the articulating spoiler is gone, the ECU still thinks it's there and I'll get a MIL light on the dash at 74 MPH. There's a fix for that when you install the GT3 factory wing. However I no longer have the wiring room for that. So hopefully we'll find which pins in the Canon plug to jump to take care of that.
3. Again, the same as item 2, the engine room blower is gone, but the ECU thinks it's still there. We think if you re-install the engine room temp senor that might satisfy the ECU.
4. I have an ABS/PSM waring light that I can't get rid of. Not sure if it's because I've removed the front diff, the axles are the same. There's a chance I can clear that with a Porsche factory OBD PST2 or PIWIS reader. I get a 525 code, insufficient data to the DME.
5. Because of item 5 I'm not getting the MPG and miles to drive on the dash display.
6. The cruise control doesn't work, I think that's an important accessory for any contemporary high end car. If I wanted a race car I would have gotten something else. This will probably be the most challenging item on the list to fix.
Renegade says they're working on these items since they have customers with the same problems. At some point there should be schematics that takes all the drama out of this.
I'll be happy to answer any specific questions, I've made up a pretty extensive list of some of the finer points. This install doesn't have to be this hard/frustrating with better instructions.
Still for me the bottom line it's a match made in haven... acceleration, reliability, easy parts to fine, and cheap. I like it because I can see the engine instead of an air cleaner.
