SW20 Starter Relay Wiring Notes
Info brought to you by Eric Hux of Hux Racing, LLC
This starter relay diagram is a complement to our diy videos showing how to simplify the SW20 Chassis Harness wiring. Pinout info is in relation to the 12 pin molex connector we detailed in the video as well as pin locations.
This is the starter circuit diagram from the 93 MR2 factory wiring manual. Please note that no matter which version you have, the starter wire originates from IE4 pin 9.
