None_zero Posted March 29, 2023 Report Share Posted March 29, 2023 Also based on this paper guide right here I'm guessing it was moving the ground that solved him. Quote Link to comment

I am trying to set one up right now and I thought I had to get it spliced in at the other side of the resistor instead of directly to the coil am I wrong about that? It's in the wire harness behind the left lamps near the coils. It's taped up and looks like a lump. I imagine all harness have them in place even if no tach. 1 Quote Link to comment

So should I be connecting my wire on the other side of that resistor or is that not how it works I'm not an electricity wizard I usually try to stick to complex jobs way out of my depth like coloring inside the lines or eating paste you know? Lol sorry my sense of humor is weird this isn't meant to be anything but a way to laugh at me 😉 Edited March 29, 2023 by None_zero Quote Link to comment
None_zero Posted March 29, 2023 Report Share Posted March 29, 2023 (edited) What I think I'm asking is do the coil resistor and tach need to be in sequence or is the fact that they are on the same circuit enough ... one more question. Do I need to have the old tach disconnected or does it matter? Edited March 29, 2023 by None_zero Add question Quote Link to comment
datzenmike Posted March 29, 2023 Report Share Posted March 29, 2023 Mixed up with another tach question. Quote Link to comment
None_zero Posted March 29, 2023 Report Share Posted March 29, 2023 Ha it works on the first try! So that's what this feels like! Quote Link to comment

datzenmike Posted March 29, 2023 Report Share Posted March 29, 2023 Another member has a tach question. I thought you were him. Quote Link to comment
Stinky Posted March 30, 2023 Report Share Posted March 30, 2023 Usually Red is hot 12v White....the light Black duh ground. Green the coil -12v, or Neg side of coil That siwtch is for 4 cyl, 6cyl or 8cy....sorry, nothing there for a V10, I-3 or etc. Quote Link to comment
