Scanmaster 2.1 wiring question

[Selfel]

I recently purchased an 87 Turbo T and am currently going though it to see what I have and what all has been done. It has a Scanmaster installed and in verifying the wiring it has the white wire connected to the ALDL connector but also has a wire spliced to it going to the ECM. Ok to just delete the wire to the ECM?

How quickly does your SM update? That could be the PowerLogger wire.

What terminal on the ECU does the wire from the Scanmaster go?

to the op
if you have a scanmaster 2.1 and it shows 2.1 on display when powered up ...the white goes to the aldl ( E)or the ecm at A8
no need to have the white wire connected to aldl plug and ecm ...its the same
if you have a powerlogger (and a scanmaster 2.2 chip installed in the scanmaster ) you should make use of the faster data stream from it and connect white wire to the to the aux block scm terminal

Not exactly sure what pin location this is but here's what I've got

I just looked up the Powerlogger installation instructions and see now that it would be obvious if I had one. I do not.

Looks like it goes into pin D-11 on the 32 pin connector. Which according to my info is a “not used” terminal.

Unless it goes into C-11 which would be the air temp terminal.

What wire is the red wire spliced to on the SM?

Perhaps Pace will know more.

 

[Selfel]

Red wire is spliced to the white wire on the Scanmaster

Subbed.

I see now that there's numbers on the connectors. While my wire colors don't match the diagram above, my spliced in red wire to the Scanmaster is on pin D11.
