My 90 chev 1/2 ton has a green wire with a plug type end that is comming out of the large wiring harness behind the distributor.it is a male end that obviously belongs somewhere.Also i was told that the brown wire for timing the engine was in this area but after looking in the large harness i cannot find it.ANY HELP?thanks
The brown wire you're looking for is behind the black plastic relay cover on the right side of the firewall.This wire gets disconnected when setting the timing.
