Blufc3s Posted May 13, 2017 Share #1 Posted May 13, 2017 HiI have a 76 280z with a 82 280zx turbo drive train, manual transmission.My backup light switch is bad so I ordered one from rock auto. It didn't fit.In the fsm it states the transmission is part FS5W71B. It turns out my transmission is FS5R90A. It appears that transmission was 1 of 2 types that came in the 83 280ZX Turbo.My problem is I can't seem to find a listing for the FS5R90A back up switch.Does anyone know where I can find this switch? TIA. Sent from my iPad using Classic Zcar Club mobile 1 Link to comment Share on other sites More sharing options...
Mark Maras Posted May 13, 2017 Share #2 Posted May 13, 2017 If the trans. case number is D3202, the OEM switch part number is C200506P01. Rockauto.com says they have them. Google the part number. Link to comment Share on other sites More sharing options...
Blufc3s Posted May 13, 2017 Author Share #3 Posted May 13, 2017 Thanks, I will checkSent from my iPad using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
Blufc3s Posted May 14, 2017 Author Share #4 Posted May 14, 2017 The only number I can find on the case is 13-52-065-901.The part number on the switch is WC-010.The 1983 280ZX FSM shows 2 manual transmissions. Mine is the FS5R90A which is a wide ratio. It's odd to me that the transmission came from an 82, but only shown in the 83 FSM. The back up switch is on the drivers side of the transmission and is bigger than the one for the other transmission, which has the switch on the passenger side.Here are pics of my switch and the one from Rock auto.Sent from my iPad using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
Mark Maras Posted May 14, 2017 Share #5 Posted May 14, 2017 Did a little on line digging for info. It appears that Mustangs and Jeeps at, one time, used the T-5. The jeep reverse switch for the NWC T5 trans, APPEARS to be very similar to the one on the left in your pic. Didn't research the Mustang trans switch yet. Perhaps a trip to the parts store with switch in hand will come up with a match. I hope the Jeep switch works for you. They're only $10.00 - $15.00.

Blufc3s Posted May 14, 2017 Author Share #6 Posted May 14, 2017 I looked on eBay and amazon and you're right, the jeep and mustang switches look similar to mine. It is a T-5 so I will go to napa tomorrow with mine to see what I can find. The connector is different but that doesn't matter.Mark, I really appreciate your help Sent from my iPad using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
SteveJ Posted May 15, 2017 Share #7 Posted May 15, 2017 Just curious, is your reverse switch on the left or right side of the transmission? FYI. Looking through RockAuto, here are some of the part numbers I found: AIRTEX/WELLS 1S5283, STANDARD MOTOR PRODUCTS LS230, MOTORCRAFT SW1694 Link to comment Share on other sites More sharing options...
Zed Head Posted May 15, 2017 Share #8 Posted May 15, 2017 Rockauto is a good place to look. And the 1984 300ZX used the FS5R90A. That car's switch should work. I looked in Electrical Switches and Relays for a 1984 300ZX. It's there. They call it the "back-up lamp switch". Might explain the difficulty in finding. But it looks like the one you show that is too short. Who knows. Are you sure that you pulled the correct switch? There are several. Maybe the one you have isn't for the back-up lamp.

Blufc3s Posted May 15, 2017 Author Share #9 Posted May 15, 2017 I am sure it's the right switch. If I short the leads going to the switch the lights work fine. I also tested the switch out of the car, and it doesn't work.When I look at the rockauto 84 switch the tip is different, similar to the one on the right which I originally got from rock auto. I looked at the tranny for the 84 in the FSM and it shows the switch on the passenger side, opposite to mine.Anyway, I will visit a parts store today and see what I can find.Sent from my iPad using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...

The switch looks very similar to the one for the T5 for the 84 mustang as Mark found, except for the leads, which isn't a problem.Sent from my iPad using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
SteveJ Posted May 15, 2017 Share #11 Posted May 15, 2017 That's what I thought. It fits with your part photos and with what Mark posted. If you look at this site: http://www.5speeds.com/t5/index.html, it will show you other T5 applications. The GM version looks like you could use bullet connectors on it, and it runs about half as much as the others. Link to comment Share on other sites More sharing options...
Blufc3s Posted May 15, 2017 Author Share #12 Posted May 15, 2017 Thanks to everyone who answered this post I now have backup lights. I bought a switch for a 84 mustang, assuming the studs were threaded, however they were "push on" studs. I ended up soldering some connectors on, heat shrinking them and tape, so it's fine. I should have used the GM switch as Stevej suggested.Sent from my iPad using Classic Zcar Club mobile 1 Link to comment Share on other sites More sharing options...
