SR20 Transmission Wiring - help needed!

Stark Auto Rentals · Postby **Stark Auto Rentals** » May 4th, 2009, 1:07 pm

Hey guys,

I have a question with regards to the SR transmission and the wiring.

On the transmission there are three jacks on it.

One has seven wires. The other one has three wires and the last one has two wires.

Can anyone advise me what these wires are for or provide a wiring diagram or any kind of information please?

ok guys, thanks for the info......

i have another question.........

what wires are required for the transmission to actually work and change gears..........

right now, none of the wires are connected and the transmission appears to be locked in 2nd gear.......it's either 2nd or 3rd i believe.

guys, here's the whole story. i'm actually helping a friend out.

He had a sr20 engine and transmission in the car.......car is a 626 btw, so no original harness and ecu and stuff.

the transmission got damaged in the car and had to be replaced. the one that was in the car was a cable type transmision.

he got another sr20 transmission and placed it in the vehicle. however, this transmission did not have any kickdown cable. Also, out of the three jacks on the transmission, only one was able to plug back in as normal. that was the one with the two wires, so i assume that is the speedo signal.

now the other two jacks are different from what is on his sr20 harness in the vehicle.

he also got a transmission ecu with the transmission and it looks like this:

my question is does he really need this ecu to be connected for this transmission to work? as it is, with only the speedo signal connected, the transmission appears to be locked in 2nd gear......

the other problem is that he did not get the plug in harness for the transmission ecu so we're really trying to see if we can get it working without that transmission ecu.

slackwire, sorry man, never went ahead with that. I purchased one of the normal tranny's instead and used that.
