The Ultimate Tacho Thread

So, to conclude:

VB-VL= signal wire to coil.

incorrect. the signal wire on a VL does NOT go to the coil! there is a wire behind the instrument cluster. the coil is a multi spark system i believe and will give an incorrect reading. in the Gregory's manual it says there is a signal wire hanging behind the alternator but that is incorrect too, it is only a test wire.

Ah yes bangers, my mistake I forgot about the rb30's. However V8's should still be able to go to the coil though right?

 

[bangers]

i imagine so as the V8 didn't have an ECU. but then like the RB30 the wiring loom may be the same for auto and manual. i can't say for certain.

Either way....the wire will always be behind the dash as well....

what about installing a stand-alone shift light?? How do you wire one of those up?

Or installing a water temp gauge, oil temp, oil pressure..

Read the instructions, there will be a signial wire that will be connected to the same signal wire as your tacho. (see above posts for instructoins on finding wire.)

Or installing a water temp gauge, oil temp, oil pressure..

A few questions there. Depends on the car, engine and gauge. more info needed.
