New to this site, and glad to have joined. Decided to rework the engine harness because of recent fuel pump problems. I noticed that previous owner bypassed the fuel pump relay and ran sending unit/pump power into bulkhead in wrong place. Just wondered if anyone had an actual diagram of the bulkhead wiring. Autozone/Haynes didn't have it. I have an 87 K5 TBI 350/5.7. Any help is appreciated.
