|______| with the clip facing up... on the wiring harness... which colour is in which side of your cars?
i have 2 cars here one is L= BL R= BR and the other is L=BR R=BL

i can't really tell which is supposed to be where on my mums car... i had it bypassed and took it out of the plug and can't remember which side should be what and which car i believe LOL

so yours is the same as one of ours... L=BR R=B
is yours 90+?

That one's from an '88 GTE. If you're talking about the smaller plug which actually goes to the resistor I don't know of any reason why it shouldn't work regardless of which wire connects to which. I'm pretty sure it's just a resistor (no diodes or caps inside).

yea i was also thinking that but wasn't sure

we're trying to troubleshoot my mums fuel system as for some odd reason she'll go for a drive and when she gets back, leaves the car for a bit, goes to go out and the car won't start - fuel pump resistor blown.. replace > repeat lol
so i bypassed the whole system and am now getting annoyed with fuel usage so returning back to 6v and seeing how it goes... and if it does blow again then i can at least troubleshoot :)

You keep blowing resistors? Are you running the stock pump on the car? I'd start looking for the cause.

it's back in for a reason

try 14miles to 2 gallons of fuel

a. 12v is using too much fuel
b. the fuel pump was on 12v ign
c. it's dangerous in an accident (fuel pump won't turn off)
d. my mums car and it's pretty much stock
e. it doesn't need it!

i did forget to mention i think that the fuel pump was rewired to ign 12v as the stock efi circuit for some reason kept blowing the resistor, which hence the pump wont turn off... or at least i dont think it will

since returning to stock i now have gotten so far 43 miles to 1.8 gallons, still waiting for the resistor to blow lol
