icon4.gif  Someone help me with SA63 tacho configuaration? (can you check your celicas for me?) Sun, 27 February 2005 23:08 Go to next message
Hi guys, I need to know urgently what side of the coil the SA63 celica tacho runs off. Is it - or + side? Need to know this as it is what determines what kind of tacho adapter i need.

Can someone perhaps check out their SA63 and get back to me on which side its on for me?

Thanks guys

Blake

does anyone know of a tacho that runs of positive side

they either run of neg side

or from output on ecu

or like a datsun where the neg coil goes to the tacho does a loop then back to the dizzy to the points

maybe what theyre askins is if its a positive signal coming out of the ecu?

no, its just that there are two MSD tacho adapters:

Current driven - + side
voltage driven - - side.

I need to know this as its an Sa63 dash im using.

Every Toyota I've seen uses the -ve side. I know an RA65 does, so I think it's a pretty safe bet the SA63 works the same.
