So it begins….wiring the R4. This is all new wiring via a Haywire kit with modifications. Due to the many customized changes on this car, it made sense to start with fresh wiring, rather than using the old harness, which would have to be sliced and diced, possibly compromising it’s integrity.
The Haywire kit is a modern, easily obtainable wiring system. All the relays are in one place instead of strung out to various places in the engine compartment. Checking relays and changing fuses is much easier.
Oh no….where do all these wires go? Not to worry, Haywire provides marked wires to keep the installation simple. With fiberglass cars, you have to add a ground wire for every power circuit. These grounds are not included in the kit.
This is a split braided loom which has a much cleaner appearance. In my opinion, taped wires or plastic corrugated loom are downright ugly. These of course, have a place on restored cars, but we’re having fun here, dressing this ride up with all the custom additions.
I had to change out the air bonnets for hood clearance. These have a lower, sleeker profile and will also be race car red when I’m done painting them.
Orange ignition wires are in place. I’m upgrading the coil to an E-core, which saturates faster, with multiple firing and hotter spark. The higher the engine compression (under boost) the harder it is for the spark to jump the gaps. The ignition wires will be covered with the rest of the stainless shielding.
Placement of the MSD box and Boost Timing Master is away from the engine heat and roadway moisture. This MSD puts out 500 volts to the coil and the coil puts out 50,000 volts to Bosch Platinum Plugs. Through the timing box, the driver can vary the timing under boost from inside the car. Lets hear it for easy to access engine tweaking!!
Brad, your website is very professional, just like your work. Your finish on my Avanti is immaculate, obviously done with attention and care to detail. It was a pleasure working with you. I would and have recommended you unequivocally.
