I just replaced the head gasket on a 1991 Celica. When reinstalling, I have a wiring harness that I cannot find its orgin. There are 4 joined wires that cross over the timing pulley. Two harnesses go to the alternator, one black harness connects to the oil sensor in the block and the fourth white harness goes..... The wire is a single wire harness, and since finishing the project, the battery warning light comes on. Related?

you know it could be easy fix but just repairing a wire or two but if you need a harness then your looking for trouble if you need anything else go to collisionrepairadvice.com its worth it

SOURCE: wiring harness for a 91 accord into a h22

That depends on what motor your accord came with, If was the f22 it does work but requires some mods. Providing that the vechile you are installing it in is OBD1 also.

SOURCE: I have a draw on the battery on my 85 Toyota pickup it kills a fully charged battery in about 2 hours... Ive put a volt tester between the disconnected positive battery cable and the positive battery

Go to You Tube Video & see how to do a parasitic CURRENT
drain test

What you have done so far with a test light & volt meter is basically
doing nothing

You need an amp meter & a wiring diagram,then pull fuses one
at a time, to get to the circuit that causes the drain,then use the
prints to test that circuit for voltage drops
