bbc engine harness
 

Looking for any bb 454 502 500 engine harness that will plug into my 500 efi harness. Block harness only. My efi harness is good

Bump

does the one you're looking for have a 4 pin connector for the efi harness to plug into ?

Ill.have to go check won't be there til tomorrow evening or mon. But yet I think it does but I will.get back to you

I have one that I was going to use, changed my mind and bought new ones. I stripped all the tape off but its all there.

I am pretty sure that is it
Best I remember mine is messing the yellow with blue stripe wire. Hine the need for a different one
But I will.get back to you tonight or tomorrow

I took a closer look at mine and its been cut on and not in very good shape,

Oh ok then I probably better pass that's one of the reasons I wanted another mine has been cut on aswell

My issue is that my harness for my 500efi mefi 3 is messing a yellow/brown wire that goes to the starter slave. And I don't know where it goes too

maybe I can help, what do you mean ??

There is a yellow wire with black stripe that goes to the starter slave selnoid that is messing from my harness . But I just found a wire diagram. It seems to change to black and attach to the ground circuit. So I think I have it figured out now
Thanks

there is a yellow striped wire and a black ground wire that trigger the starter relay, the yellow one comes from the key switch or toggle on the dash and the black one is common to the ground bus

Yep that's it thanks. Figured it out once I got the right diagram
