There was a thread here a while back, but I guess I forgot to print out the info sooooo: Can anybody tell me the size and location of the hole in the firewall for the factory grommet used on a 70 B body with a tach? Pics? I think it's right next to the bulkhead wiring block, but.... Thanks Dave

Thanks a bunch! hmmm, not where I thought it'd be; is it a factory tach car? What is the cable directly opposite the firewall bulkhead connector? Cheers, Dave

Blue and black wires next to gray tach wire are for the headlight door system on a 70 Charger. I am not sure about the other cable/wire you are questioning without having a look underhood.

Dave,
Here is another picture of a tach wire. It only adds more confusion. I guess I would like to see a few more unmolested cars to confirm.

This is where the tach hole is drilled on my 70 GTX. It's a factory tach car. The hole diameter is about .830".
I currently have two Super Bees in the shop, a 68 and a 70, both are original tach car and both have holes in the same place as your GTX. Mike

Well, we have 3 different locations listed but three cars which people have stated are original tach cars have them in the same spot as the pic of the '70 GTX, so that location is in the lead so far! Thanks guys; if anyone has any more info or pics; lets see 'em! the holesaw is coming out in the next couple of days! Dave

These wires are for 70 Charger only. They run the headlight motor to open the doors. You will not need them on a RR. New harness must be generic. I would tape up the connector and even possibly tape this entire pigtail to your harness under dash.
