Trying to hook up a tach cable to my 76 SRX with a 78 motor. Can't find where the tach cable connects at the motor area. I was surprised to find that the speedo cable connects to the water pump.
SPEEDO CABLE GOES TO AXLE BEARING HOUSEING UNDER SECONDARY. TACH GOES TO WATERPUMP. SHURE SIGN YOUR WATER PUMP BELT IS BAD YOUR TACH WON,T WORK. 3:16 (yammie tony)
Haven't had much luck getting new ones. I found 3 aftermarket ones at a swapmeet last year. Bought them all. If you do find a source for them let us know.
