sr20 wire harness differences

[skyline084]

Hey guys,

I picked up a wire harness for an sr20det years ago and cannot remember for the life of me if it was for redtop, blacktop or anything. I take it they are different? and what makes them different?

Early model red/black should have the same harness, however late model Kouki 180sx blacktop is different.

cool, thanks guys for the fast response. The harness is in my trailer, going to pick it up this weekend.

redtops use the grey and brownish/red connectors to connect to the chassis harness. Idk if thats any different on newer harnesses

Look at the ecu pin out

harness is the same the only difference between the 2 is they use different o2 sensors but the sensors plug into the harness the same, im running a blacktop harness with a redtop ecu and redtop motor, no issues
