1971 mazda R100 wiring help
#1
I working on a 1971 Mazda R100 someone cut the harness and I have a hand full of wires I can't find on the diagram the car now has a s3 12a engine and 79 transmission here are some pictures and a list of wires I need to figure out
Blue - thermal sensor
Blue red - thermal sensor
Black yellow thin- starter
Black yellow thick - starter
Yellow white - water temp
Yellow red- oil pressure switch
Green yellow- reverse lights --lights only shut off in 5th gear
Red yellow - reverse lights-- lights only shut off in 5th gear
Solid black--?????
Solid white--?????
Solid yellow-?????
Black white - alternator??????
White black - ?????
White red -- alternator
I think most of this is right I cant seem to find a wiring diagram that is consistent with all the color i have to work with

The 5th gear switch is up on the right, the reverse switch is lower on the left (USA drivers side) and may have red wires.

I believe it is a 1980 5 speed trans the switch has no wires on it just two bullet style prongs that come straight out of the sensor like the Rx2 transmission switch . It's located on the left side of the tail shaft (driver side) 5th gear switch is on the top left (driver side) of bell housing behind the slave . Both switches react in the same matter on shut off light in 5th.

Got my reverse light issue figured out transmission had three switches and the owner had removed the reverse switch since he was having clearance issues .......... 30 min a hammer and a reverse switch later and it works !!! Don't try this at home I recommend sourcing out a Rx2 -Rx3 transmission if you can ( it will fit inside the narrow tunnel ) lol but now WTF is the sensor on the tail shaft housing for ??????

you will find wiring diagram for the rx2 which is the closes one, all kinds of free manuals for the Rotary

Thanks Tonka I figured out the problems the rx2 wiring was to different to use basically the only wires that were the same were the ones that I already had wired so I ended up having to trace the rest of them back and few wires I had to eliminate which were for the alternator regulator since the new one has one built in
