1jz swap speedometer help

[supr88]

I have swapped a soarer 1jz with the automatic transmission into my 88 supra, and am now in the process of hooking up my autometer electronic speedometer. Can anyone help me identify the wires used for the speedometer? There are two different speed sensors in the ECU pinout Sp2 positve and negative, and Sp1. Which wire can be used for the speedometer signal?
thanks for the help.
Mike

i figured it out. i discovered that my 3 wire speed sensor is not working, going to troubleshoot that to get my ECT working properly. I used the 2 wire sensor, the colours were pink and purple to hook it up, spliced the wires from the ecu plug.
