Tranny Position Sensor...yep...that be it:histerica

 

[colinlesser]

so i dont need it right?

Yr call on that one...backup lights are nice to have..but there are other ways to switch them on/off and rear floods are better than the stock lights anyways.

..of course if you have the reverse ignition interlock (RII) feature on your Durapsark module, the engine will die if you try to put it in reverse without that switch hooked up.

i have the duraspark but it doesnt die in reverse

.

wiring a relay between that backup switch and it auto turns yo rear floodlights on for ya. YOu could also put a switch in the dash then for auto/off/ manual on....At least thats the way i did it

where could i get a harness for that and what would it be called?

 

[85f150]

harness for extra lights? Just buy an accesory wiring harness from your local parts store or from Summit or Jegs, make sure it comes with a relay. I run the el cheapo walmart plastic square lights for when they brake i don't care too much. IIRC it came with a harness and relay, i just had to make everything longer
