[Black331Stang]

hey, hope everyone had a good holiday...i got a tach and i tried the search with no results and that thing is a pita anyway...
anyway..what is the best place to run the red 12V wire to? fuse box, + coil, radio remote turn on? if u suggest fuse box, which # should i go to? and did u guys drill a hole for the tach wire or just run it thru where teh throttle cable goes?
thanks for any help.

I just hooked it into the radio on the fuse box. Don't remember the # off the top of my head though. I ran the green wire that goes to the coil through the grommet already in the firewall where the factory harness goes though.

I just soldered the green wire to the negative side of the coil wire (can't remember the color off hand). There was already a slit in the soft rubber part behind my gas pedal, so I just ran it through there. I hooked the positive side to a 12v source on the back of the fuse block (with the key on).

u can just pinch the wire behind the fuse right?

I think I used a spade plug if I remember correctly.

o, can i just tap into the remote turn on wire behind my stereo?

I don't know about that. I just unbolted the fuse block and tapped into the open lines that were there...

tapping into the radio harness is fine as long as its a switched volts. you hook the tach output wire to the green wire on the coil. hope this helps?

oh yeah, you may want to revise your auction on ebay! Ebay rules are, "you can't list an item and offer it as a trade off of ebay." I only know because I did the same thing and ebay contacted me and ended the auction, cancelling all bids. Just looking out for you...
