I'm 19 and only 5'8 and 150lbs and i hate getting under there. And theres too many damn wires for me to know what is what. Thank God i got a factory manual!
As per the same message at Stangnet.com:
Throw those Skotch-Locks away! They put you on par with the yard boy at the local U-haul place.
In your year car, the Pink resistor wire plugs into the red lead with a bullet connector. This should be sitting right above the driver side courtesy light. make your self up a short "Y" with solder type bullit connectors, so that you now have a tap for your key on power source.
Very clean, very easy, and very professional.

I don't have a picture so hopefully I can explain it.
What you want to do is take two pieces of wire about 2" long each.
Get two female bullet connectors (by the way thanks for the spelling correction. See we all learn something!), and one male bullet connector. I prefer solder type connectors, and shrink wrap, but if you aren't comfortable crimp connectors will suffice until you learn some good soldering skills.
You want one end of each wire going into the one male bullet connector. The other two ends will each have a female bullet connector. If you hold up what you've just made, with the male bullet connector at the bottom, and the two female connectors at the top, it will look like a "Y" with a real short base leg (the connector), and two long arms (the wires).
Disconnect the pink wire from the red wire under the dash. Connect the male bullet into the red wire's female bullet. Connect the pink wire to either of the open female bullet connectors on that beautiful "Y" connector you made. Connect the other open female bullet to your tach wire requiring Key on power.
BTW: in that same area is a light blue wire with a red stripe that has a three headed female tap. This is your dash light accessory tap, so the hot lead for your tach light plugs in there.
HTH,
Scott

Don't connect anything to the Pink resistor wire. that is the same as the positive side of the coil. You do not want any additional load on there or you may not get correct voltage to the coil. Are you using a volt meter or a light? Sounds like what ever you are using is putting too much load on the circuit. A light is all you need.

haha I didnt know you and 66runt were the same person!
So Scott, do you agree with 67t5 about the extra load thats being put on the coil?

I agree if you were to connect at the coil, or try running something that pulls more than the miliAmps a tach does. If that tach pulls more than 100mA I'd be very suprised. If the rest of the electrical is good, that wire is capable of carrying an additional 5A. I'd limit a load to 1A using the "Y" connector, then you know you've got plenty of room. A coil will pull between 5-7 amps without the engine running. Running it will average 3-5 Amps. The circuit from B+ up until the pink lead can carry 10A easy.
***Edit for clarification***
"That wire" I am talking about is the Red wire coming from the ignition switch and connecting to the Pink wire. As 67T5 said, you don't want to tap "into" or after the pink wire.

Yeah, I signed on here before I really understood about how to have a cool "handle", like all you smart guys have.

Good man!
Do it once right, and forget about it!
Do you need help finding any of the other taps? and were the instructions good enough for you to understand how to make that "Y" connector?
