ok well i took a lower harness out of a 5 speed 1990 240sx
I’m putting it into my previously AUTO 1989 coupe but for some reason one plug is totally differnet.
theirs three plugs on the front of the relay box that fit but then theirs a plug facing the back of the car under the relay box that is different than the one off the 89
The 1990 plug (coming off the lower harness) has 4 prongs and the 1989 plug (coming off the engine room harness) has 2 prongs Wtf
the coupe used to be auto does this make any difference?
CAN THE 5 SPEED HARNESS BE USED ON A PREVIOUSLY AUTO CAR ?
is it the very bottom plug on the side of the engine fuse box?
Shift interlock (park) sensor… IIRC.
Its been a while since I did mine, but I had to splice the 2 wires together to fool the interlock device into thinking it is always in park so that it allowed me to start the car…
You may want to search auto -> manual swap on zilvia or something to be certain…
