ok so i belive its my speed sensor and my odometer sensor that the wires are broken on my trans. so i go to an aoutoparts store and the guy dosent know what it is. but i replaced a reverse light swicth in my last 240 and they all look the same. sooo dose it matter what sensor? could i just buy 2 reverse light swicths and would they do the job?

 

ok so i just redid the wiring and they work now. when i got the car the HUD didnt work, but after a trip to the junkyard and crossing my fingers the junkyard HUD works even after water damage. but it wont read anything it just stays at 0. could that be the speed sensor or cause it came out of a SOHC and into a DOHC?
