R33 s1 converting to s2 transmission

 

Hi guys and girls  I got a 93 r33 s1 I'v blown up the auto transmission I got a new one but they gave me a 95 s2 one of the plugs has got an extra wire going to it I think it's a eath but not sure does anyone no what it is? And can anyone tell me what colour s1 wires go to s2 wires?

Thanks in advance  advance    s1 ?

s2 ?

Double check that its going to work first. Some cars had the auto ecu in the engine ECU others had a separate auto ecu. Don't know if this a a problem for you but do the research first.

For anyone trying to do this I figured it out  the s1 transmission has a 7 wire plug and the s2 has a 8 wire plug but where it plugs into the main harness in the engine bay that plug has 8 so you just have to run an extra wire from the engine bay plug to the spare s2 transmission wire
