Tachometer Firewall hole location?

FC7Demon340 · Feb 8, 2020

Can someone show me where the tachometer firewall hole location is on a 71 Dodge Demon? My 71 340 Demon didnt come factory with the tach. But I'm adding the factory tach and factory harness. Just dont know where the wire that goes to the coil goes through the firewall.

You make your own hole any place you like.

I’d saved this from another post. Pretty sure it’s for 71 as I “believe” there were differences between The years. If the hole is not there you’ll have to drill it. I just used an empty spot on the bulkhead connector. The one that shows plugged was for the manual foot pump hoses for the windshield washer.
