I was just wondering where you guys ran the wires through the firewall, if theres a place already there so I wont have to drill. Where did you wire it to for the lights in the guages? Where should I attach the vacuum line to? Between the intake and fuel pressure regulator I assume?Let me know guys!!! pics would be sweet if anybody has them.

I ran my wires through the grommet that was already in the firewall, comes out right below and next to the brake booster just like LoudToy said. I ran my lighting wires to the park lamp, MUCH easier than splicing into the headlight switch. Good luck, get us some pics when it's done!
LoudToy958 said:I ran my wires/tubing through the port where the hood latch cable runs. Its kinda tricky under the hood, bacause it comes from the fender right near the brake booster. It may take a set of needle nose to pull the wires through.
As far as the fuel pressure, mine went right to my FPR, but you can use the fuel port on the rail with the correct adaptor I think. I have seen it done in 5.0 monthly a year ago. As far as the wiring, I wired my pillar to the headlight switch, just need a meter. I don't know the wire colors off hand, but I am sure someone here does. I ran my vac line to the A/C vac line off the T on the drivers fender. SEE PIC - I just bought a T at autozone. If you do this, don't push the tubing in till it stops. Leave it room or it will not read.
Hope this helps a little.....

Vac is great to have. It is a must on a SD car, like my 88.
Good luck.

That does ring a bell but that means nothing. that color combo sticks in my mind because on an early aero fox, that is the color of the wire from the headlight switch to the MF switch. That could be why it sounds familiar.FlyBy763 said:Does a red/yellow wire ring a bell? Ive been trying to decipher my electrical diagram in my Haynes manual...should be a fun time to figure out which one!
