‘89 IROC, originally 700R4, changing to a T56.

Thanks.

PS -original member who couldn’t recover his login details.

I think in 89 it was on the transmission tail housing. Do you have a Vss buffer next to the ecm like this ?

I’ll have to look. Thing is I only recall one plug on the 700, I’d though was for converter lock up, so will get eyes on it tomorrow when the rain stops.

Thanks.

Did you have a speedometer cable ?

behind the speedo on '89 camaro

Yes. I have a cable. So must be behind the speedometer.

thanks.

you might contact them to see how it works with a t56. I can’t get their calibration instructions to load.

Thanks Brian.

So I found via google this site

http://t56cablespeedometer.com/

The reviews link back to TGO.

This may be the way to go without running the box/wiring from VSS to VSS.

When I get a reply back, I’ll update the thread.
Thanks all!

So I thought I’d update this thread, Alloy is still doing the conversion, this allows me to retain the original VSS.

A lot easier in my mind
