TBI wiring questions

[lak2004]

Ok trying to get my wiring all finished so I can move on the next project. Couple of questions though

There is a pink/black wire, is this what I run to ACC+ with a 10a fuse?

Do I use the tan/white wire coming off of my fuel pump relay(factory) to send 12v+ to the fuel pump? Do I also need to run it to my oil pressure switch?

Thanks guys!

PM bp71k5. He installed a factory TBI harness into his 1st gen and should be able to help you really quick.

Thanks Scott! Was being a little lazy when I posted to see if I could get a quick answer when it was still daylight out.

But I just found all the info I needed using the magical search feature!

Too bad it is dark and cold now

Well, considering the price of gas between March and now that's probably a good thing. If you were saving the money that you would have spent on gas you should have a good amount of cash to drop into the blazer now.

The big word in that was "IF" I had been saving.

One day I will learn how to do that.

In case the info is useful to other lazy people (myself included).

There is a pink/black wire, is this what I run to ACC+ with a 10a fuse?

Yes. There's also a constant power hookup that the larger orange wire needs to be connected to.

Do I use the tan/white wire coming off of my fuel pump relay(factory) to send 12v+ to the fuel pump?

Yes, mine was solid tan though, or the white stripe was worn off.

Do I also need to run it to my oil pressure switch?

I didn't run the oil pressure switch, but if you do, it's output needs to be hooked up to that same wire so it can power the fuel pump if the relay goes bad. The power to the oil pressure switch comes from the same big orange wire that powers the relay.
