1990 4.3 wiring diagram

[dwayne80]

Changed motors due to a cracked block, same engine but don't know where a single wire goes, if someone knows where a 4.3 wiring diagram would be, be much help. The color of the wire is solid light blue, it's joined in a sleeve with a white wire with a blue stripe on it, that's connected to the back of the distributor. Boat will not fire. thx for any help.

In the future Butch, start a new thread of your own, don't hijack someone elses thread for your question.
