tacho conversion for TS into 105 which wires?
Hi Guys, could someone identify the red, yellow and blue wires in the photo below.
I have used the tacho guts from the 75 and mounted it to the 105 dial and I'm not sure which wires are which. Assume 1 is ground, one is signal and one is positive?
I have read the brown/white wire on the engine loom coil connector is what I should be hooking up to.
Any help greatly appreciated.
