Re: '89 fuel pump wire colour

Nice write up.

My 1990 FSM shows AT THE PUMP--RD (red) positive, VT (violet) gauge sender, BK (black) ground.

Changes to:

PK (pink) positive, TN (tan) gauge sender, and the ground doesn't matter.

So, in summary, if the 89 is like the 90 you want the pink wire.

That is one of the things on my "to do" list, and I think I'll "to do" it tomorrow.

Buddy of mine up in Eugene, Oregon says there have been a number of lifted XJs stolen there in the last few weeks.

Good luck.

Re: '89 fuel pump wire colour

Ok, my Haynes (which I consider less reliable) shows a four cylinder 86-90 with a orange to pink/white to orange wire.

Haynes for six cylinder 87-90 with a orange to pink/black to orange.

Back to 90 FSM--you don't have an MJ do you? Shows a RD to RD to RD all the way.

Re: '89 fuel pump wire colour

So it is orange at the B pillar? Is your 89 a four or six?

Residual pressure in the system.

Did it die?

Re: '89 fuel pump wire colour

I LOVE IT!

There is a S--t load of wires in there.

My fuel pump positive IS the 14 gauge pink with black stripe. The only other large gauge wire I see in mine is brown with white stripe. As far as I can see all the other wires are of 18 gauge or thinner size.

Hey, glad you got it!

Make sure you make clean and tight connections--big fan of soldering here--and heat shrink tubing or tape it up tight.

Good luck.

BTW--is that Lethbridge Canada or California?
