Hey all,
I'm trying to wire in an hour meter to my 1978 Mercury 800. I'd like to run it into my wiring harness, which has seven wires: black, white, grey, orange, red, yellow and brown.
Which one is the accessory wire? And am I correct in assuming that it would power the meter only while the key is in the "on" position?
Thanks!
