I would think so, but just dont remember all the details. My first
Mustang of that era had a Trico pump, IIRC, which was
activate by your foot.
The earliest GM pumps that I can remember were mounted
on the wiper motor. Although it should be easy to find the
connections, those washer systems were prone to problems,
and it might be a whole lot easier just to rig an aftermarket
unit and bypass the GM unit.
I'll take a google and see if I can find some pictures.
I found the pump kit, and some universal alternates, as follows:
Now, this sort of supports the suspicion that I have that this pump is a
part of the
Im sorry but have no access to the wiring diagrams to be able to help
the actual wires.
Original wiper motor + replacement motor I recently installed have
pump integral to wiper motor.
New wiper motor washer pump does not operate -- no usual clicking
noise when pump successfully activated - even though wiper motor
I suspect juice ( electricity ) not getting to activator of washer
pump on wiper motor -
so I bought aftermarket electric pump - trico - I'm wondering what
wires to wiper motor operate pump section - so that I can connect
Thanks for replies.
OK, now the question makes more sense... I'd suggest starting by doing
some diagnostics to determine whether the wash 'signal' (voltage) is
getting to the (new) motor or not. If it is, then the solution should
be obvious. If not, you'll have to dig into the circuit, though I'd
suspect the washer switch first, then any inline connectors.
See if you can find a schematic of that circuit, perferrably one with
connector pin numbers, that will make (your) life much easier.
Old, replaced wiper motor/pump assembly was balky as wiper but washer pump
worked fine when activated - therefore switch is not suspect.
I believe wiper motor gets voltage all the time when key in ignition or
acc. setting, and motor activated by switch providing ground when pushed
Therefore what I'm looking for is 2 wires to electric aftermarket pump -
- voltage all time when key in acc. or ignit. ( on ),
- and wire that provides ground when wash button on dash is pushed.
The trouble with this vehicle is that visibility + access to wiper motor +
wiring is minimal - under dash, over brake pedal.
Any info re. which two wires satisfy above description is appreciated.
Otherwise I'll do it the hard way by measuring with VOM at different wires .
Again , access difficult + wipers moving on windshield during
experimentation requires constant application of water manually + limits
duration of each test.
