I have 87 gxl and i was checking the starter when i came across three wires. 2 were not plugged in and the 3rd seemed like it was cut.

the 2 wires that weren't plugged in were black/red and red/yellow both plugs were different seemed like a male and female plugs.

the 3rd wire which is plugged was cut off towards the end like it was coming from the starter. That wire is coming from the set of wires that are connected to the alternator.

I was looking a the wiring diagrams but have no clue on how to read them. So if anyone knows where these wires belong please let me know.

thanks,

Those are NOT for the starter. A starter has the main battery ground (-) attached at the bottom mounting bolt, the main positive battery lead connected onto the solenoid, and the small trigger wire clipped on solenoid. There is nothing else.

If this wiring is in the area of the transmission, it is probably for the 5th gear/reverse switch or neutral switch on the trans. These switches are on the tail housing on the side and back.

ok so i checked to see if these wires where 5th gear/reverse switch or neutral switch on the trans like you stated. but they do not reach that far, when i pulled them out they were tucked behing the starter close to the engine far from the transmission. these were the red/black and red/yellow wires.

the one thats cut of was just hanging from another plugged wire which was coming from the set of wires that leads from the alternator.

I will take pictures and post them asap you guys can be able to better understand and assist me. Since i know nothing of the wiring system on the rx7. i tried reading diagrams and what not but still dont get it.

If the Black/Red wire is by itself in its own plug it might be part of the Sub Zero system and the B/R wire would plug into the Sub Zero sensor which is screwed into the oil pan. To make sure this is the wire you could locate its other end at the Sub Zero motor located bolted against the passenger side of the firewall and do a continuity test and if it rings out properly then you know it is this wire. If so, it is not necessary to have it hooked up.

Additionally, if the 3rd wire that you say comes from the alternator, well, there are two wires connected to the back of the alternator where one is Black/White while the other is White/Black. Which color is it?

And the Red/Yellow wire you speak of are you certain it is not Yellow/Red instead?

ok i will try what u stated above, and that 3rd wire is a thin black wire and the other one is yellow/red sorry about that

The Yellow/Red wire is likely for the Oil Sender. The plug for this sender is about one inch long, rather thin/slender and has an open slot on one side that slides over the sender's tip.

The Black wire that you state runs from the alternator likely has a White stripe on it. If you are "certain" this wire comes from the back of the alternator where there is a two wire plug, B/W wire and W/B wire then the B/W wire runs to the fuse box inside the car and specifically the wire runs to the 15 amp Engine fuse and this wire is imortant.

alright so i finally had time to work on the car and what you stated about about the yellow/red wire is correct. The only thing is now i cant find where it connects to lol

here's an update on the thin black wire, so i started following the wire to see where it comes froms and here are the details.

I traced the wire backwards and followed it to the set of wires that come from the alternator and CAS, it's like the CAS wires from the plug (colored), go into one of the big B/W wires. So my guess is that the small thin wire might have to do something with CAS? since the car cranks and does not start just sort of backfires.

Another thing i came across yesterday, i checked my fuel injectors and the were sort of dry but the fuel rail had gas in it. i had changed the fuel injector connetors because the old ones were just destroyed for some reason. So my question is,is there a positive/negative wire? or can u just connect them however?

i will post pics as soon as i get home since im in school at the moment.

The Cas has a Green, Blue, Red and a White wire and no other wires. Are you familiar with how to do a continuity test? And the Black wire you speak of likely has a stripe on it so find what color this stripe is even if you have to resort to cleaning part of the wire so you could identify it. The Oil sender is below the oil filter so slide the plug over the end of it and you are done with it.
