I have a 1991 SPI - I think it was originally spec'd for Germany.
A few years ago I picked up a Specialist Components Plug & Play ECU. The SC ECU has the standard big plug. My SPI is an early one and has 2 plugs. The standard big plug and a smaller one with just 3 wires. I am just now getting around to wanting to install it.
According to the website you can move the 3 wires over to the big plug.
Problem, in the last few years I have moved a few times and I cannot find the instructions on what pin locations to move the 3 wires too.
I have reached out to SC multiple times to have them re-send it. To date all I have received is just a few random pics of a wiring harness.
I did find a did notes.
Green = 18
Grey = 7
Black = 29
The color references the color of the wire in the small plug. The number references the position of where to relocate that wire in the big plug. Green and Gray are no problem as those 2 pins are open on the big plug.
It's that last one that is concerning me. On the big plug pin location 29 already has a wire in it.
I am assuming that they may both be ground wires and I could just splice them together. But, I am not 100% sure.
Anybody know?
