EG; Wiring in external taco..

[Rivic]

ive brought a digital taco for my eg its got a earth, power and one other green lead which obviously goes to your taco, anyone help me on which wire to hook up to on the back of the cluster?...

Find a wiring diagram for your cluster and go from there. You will then know what wire is what.

Basically, you connect it to the signal wire which is usually a solid blue wire going in to the back of the instrument panel, tap it in to that.

can ya get wiring diagrams off the net?

its a blue wire on the left hand plug-harness thing, about 8 wires down or so.

^he knows, he has one in his car :p

Or you can run the wire through the firewall and onto the plug the arrow is pointing too on the pic below.

This saves having to take the dash apart.

Its located on the back of the drivers side strut tower

need some help! dunno if its the tacho the prob or wot.. ive connected to the blue wire at the back of the instrument cluster and just had the earth and power wires from the external tacho i just powered off a spare battery ive got.

now,
whern i start the car (before i start it its lit up cause its powered from the battery) it flashes all numbers like its not reading properly then jsut turns of.
the tacho in the dash works fineand dunno if its a problem with my external one or should i actually wire the power and earth from the tach up properly. is it not working cause its powered all the time or shouldn't matter?

hope ive made sense n someone can shed some light to help me!

take it to an auto sparky. they can check out what you have done and correct it. shouldnt cost too much.

Try tapping the RPM from the ECU, that's how i did mine

u just have to hook the ground wire of the tacho up to the vehicle ( & power wire in such case). it needs the same common reference voltage(ground point) as the dizzy to read correctly.

i would have thought that it would be the purple wire at the back of the cluster as it was in my old ef and other jap cars i have worked on.

get urself a multimeter and disconnect ur instrument cluster. test each wire at the instrument cluster plug while revving ur engine. u will find that the correct wire will show a varying voltage on the multimeter, problem solved...

It is blue,but usually a darkish blue,spose it could turn dark purplish with age & heat.

Dont need a multi just trace circuit board on back of cluster from tacho signal pin to pin on plug to find correct wire.
