OSS(speed) sensor, which you need, will have a dark blue/yellow stripe wire, also grey/red wire
ISS sensor, which you don't need, will have grey/orange wire along with grey/red, most sensors share that grey/red wire, just FYI
DTR connector will have a Purple/orange stripe wire from Cab fuse 2, that key on power for Reverse Lights
There will also be a black/pink stripe wire, that's OUT to Reverse light bulbs
You will need to wire those 2 wires to the 2 wire connector for reverse light switch on the manual trans, order doesn't matter, switch is either open, no lights or closed lights on
On the DTR connector will be a Pink Wire, thats from cab fuse 24, only has 12volt with key turned to START
And a Tan/red wire, that's OUT to starter relay in engine fuse box
You can just twist the ends of these wire together, to by-pass Neutral switch, or run then to the Clutch switch in the cab so starter motor will ONLY work when clutch pedal is pressed down all the way
