Top Harness

There are two main harnesses on the SVX's engine. The "top" one mounts to the bottom of the intake manifold, supporting the six injectors, PS switch, TPS, two idle controls and the EGR, canister purge and IRIS activation solenoids. Since the IRIS and EGR are out of the picture, I figured that I'd eliminate their elements in the harness.

One thing that was interesting was the amount of extra wire that led to the passenger side injector leads. I'm not quite sure what the rationale was behind that.


I removed the wiring straight back to the connector, using a very small screwdriver blade to pop out the two pins that wouldn't be used anymore, and I stuffed some RTV black in the holes where they used to be.


Substantial mass reduction? No. Necessary? Probably not. A cleaner install? Absolutely.
