Ray, personally I don't recommend messing with any of the ECM's wires. If your back in the seat area, tap into the brown wire which goes back to the tail light, it is switched.

EDIT: Correction for 1800's it is the Black/Brown wire :D

The power for your tail light comes off fuse "B". FYI fuses A, B, C, and D are all switched circuits with your ignition key. You could tap into any of those wires and the line will only be "hot" when the key is on.

He's right Ray the ECM are very fragile. I used the blue/white wire in the bucket myself. I believe that's what it was intended for and won't effect the circuits during start up.

Grrrr....I hate this electrical crap. :(

Can't find a black/brown wire....2 blacks and 2 browns but no combo.

Wish this was plug n play, hell I have not even started into the diode crap yet.
Ray, you should be able to find it coming out of the bottom of your OEM fuse block. Second fuse in should be a red 10A fuse with a Black/Brown wire coming out.

Put a relay on it if you use the headlight wire, if not it'll burn out the starter switch (I found out the hard way). Not sure if the tail light would need the relay as well, but it couldn't hurt for five bucks.

I'm not sure if it was the horn or the installation kit that had the relay but I have a rlay on mine too. The kit is a great idea since it has the correct sixe wiring already installed.

You can get a circuit sniffer at the big box store the beep when power is detected it really help to trouble shoot simply turn switch on and find hot wire turn off and see if it goes dead. there about $15 well worth the money an no need to poke or cut a wire toi test if it is hot or not works on all types of wiring from MC to in house..

I used to be afraid of wiring too Ray but this crew has talked thru things I would never have figured out on my own. Now I do try it myself first cause I know I have a plan B in the wings.
