I know this has been covered 1,000 times but I didn't find an answer to my scenario.


Car is a 98 EX, I have a rywire harness with a p28. Most of what I've read talks about wiring the reverse switch into the large black wires on the auto shifter 14 wire plug. My harness has the plug for the reverse switch already on it. I am not sure if I need to do additional wiring like splicing those two large black wires into something to make the reverse lights work.

Also I don't have the switches on the clutch pedal assembly hooked up, I have them but I don't want to have to press my clutch to start the car so I dunno what I need to do, if anything before I get a signal at my starter.

I disconnected the blue lockout box under my dash like I was supposed to, the lock pin in the ignition column I didn't but the key turns fine and can be removed without doing that so I dunno what's up there.


Mainly I'm trying to start my car, I don't care about reverse lights now but it would be nice to know down the road how to wire that up.

Thanks

 

Speaking as someone who put a truck into the back wall of someone's garage that way, don't do that. It will come back to bite you in the *** at some point.

 

OK, well I'll keep that in mind

 

I havent ran a clutch safety switch for 3 years lol. When I did it IIRC there is those big black wires one black w red stripe and one black w white stripe. Tie those two together with the wire that goes into park or neutral to trick the ecu.
For the reverse wires theres the yellow wire and the green and black wire. Run wires from the reverse sensor inside the car to the yellow and green and black.
Good luck!

 

you run the reverse wires from the sensor on the trans all the way to the shifter plug hopefully they cut the selector and left the other side of the plug to splice together so your not hacking your dash harness.. its a blue and black wire needs to be grounded so just spice it to the black wire and your key will release. the two big blk/wht and blk/red need to be spliced together. and reverse as bomber said above yellow to yellow and green n blk to green and blk on the plug. goodluck

 

the wires from my reverse sensor are inside the loom on my rywire harness, which I dunno if they already have it set up to go into the right pin on my p28.

 

Soo tie it in and see?????

 

The reverse wiring doesn't go to the ECU, neither does the starting circuit wiring.

Like someone else said, extend the yellow and green/black wires out to the backup light switch on the transmission.

 

I'm more confused as to where the wires from the reverse light switch are going to now. Everything you guys said makes sense but I'll have to try to figure out tomorrow where the wires go.
