It's pretty simple wiring I reckon - a big kill switch on the dash (new one ordered) and a Start button. Twin fuel pumps whirring away nicely.
Problems after rebuild were: Volt meter reading low on fire up then at some point down the road it would jump to 14V at random. It's never revved past 5K without a loud bang and going into limp mode. Made doubly bad as I have a paddle clutch that needs run-in and I can't use proper boost. Arggh!!
Now you have said it's a re-built rally car and the wiring has been altered I would say that could be where the problem is. What ecu has it got? The problem with only revving to 5000rpm and going into limp mode could be ECU related. The paddle clutch should be good to go from fitting. I have had 2X 6 paddle clutches and neither of them needed to be run in. I have had a hydraulic system fitted and there was just a bit of adjustment to the length of the push rod to get it just right but it worked straight away. Hope you get it all sorted out without to much hassle.
