Would I be able to just send power with a battery to that white/pink wire and see if the tach jumps without cranking the engine? As im just trying to see what wire goes to the dash, I already have my ignition setup and wire for tach with the sniper efi I just need to know what wire actually goes to the tach as its unhooked right now.
Yes like I wrote earlier, theres 2 yellows coming from the connector that plugs on the coil, and 1 red/green. One yellow turns to white/pink and goes to the black connector by the stock ecu and the other goes to that rectangular harness connector (which I don’t remember where it plugs in) and the red/green seems to be a power wire as it goes and mates with other red wires. So im thinking that white/pink goes all the way to the dash as it comes inside the cab but I just wanted to make sure before I wire it up.
I am not using the stock engine harness though I just looked over at it and thats what I found coming from the ignition coil, I still have the in cab harnesses though which im using for a few functions and was wondering which one of the connectors/wires to tap my new tach signal into as I im not fully sure where the previous tach wire lead up to.
Yes, I would just need to find the right wiring diagram but it seems hard to find for these, ill look for a wiring book eventually, I might just start it with my tach input wire plugged in the white/pink to see if it works, I can’t see it having too many options as it is one of the wires that would go to the coil.
That's my thought. Even just cranking with no fuel should get you the input you need.
