I’m installing a Holley terminator x max on a 91 Silverado with a 5.3 swap. I didn’t do the engine swap and the wiring is a bit of a mess. The terminator has a tach output wire that I can connect directly to the factory tach but I can’t for the life of me get my hands on tach wire. I can’t tell where it goes to follow it to a connector. I’ve sliced my hands to shreds digging around behind the dash trying to find this thing and I’m at my wits end. I don’t want to disassemble my dash any more than I have to because it’s falling apart. If you can show me a picture you’d make my Christmas fudge list! Thanks in advance for the help.
