On the Early 1990s the wire to cut is RED (
there is no 12 gauge purple wire)
Starter Relay, Wiring Harness, and Plugs Tricks
I locate the Relay UNDER the ECM which is right next to the wire harness/wire to be cut.
60 / 80 AMP RELAY SPDT SINGLE POLE DOUBLE THROW NEW 654
Installed under ECM and in slot between brake booster and fire wall (perfect place for location of Relay).
Wiring modified a bit to assure Pin #87a is not hot at any time.
Pin #30: Purple wire to starter (use 3/8 inch connector on relay).
Pin #87: Red wire battery positive 12v use 3/8 inch connector on relay (connected to battery positive multiple connection post).
Pin #86: Battery ground (1/4 inch connector on relay connected to ground where battery 12 gauge wire grounded).
Pin #85: Purple wire from ECM use 1/4 inch connector on relay (
Red wire on early 1990 ZR-1).
Pin #87a:
Not hot at any time and not used.
Insert a short 1/2 inch long section of plastic hose
over the center connector on the Relay which is NOT
used in this application.
