Re: Need help with LS wiring

We had a little more time today to play with the voltmeter. Got the rest of the wires figured out.

Figured out that the the pair labeled (1) two red/white stripe wires are power to the generator battery control module.

Figured out the first relay puts power to the injectors, coils, transmission pin E, and 02 sensors. Seems like a lot for one relay to handle but that’s how they did it. Is it common to run all this off of one relay?

The second relay is for the fuel pump.

The pair labeled (6) Orange/black stripe and blue also goes to the generator battery control module.

Still cannot find a battery control module for sale anywhere so I’m not quite sure what to do with all of that system.

Also confused at whether to run everything off the two relays or try to split the systems out and put them on their own circuits.

Seems like it’s taking me forever to figure this stuff out wish I had more time to dive into it.
