Just traced my TDC transmitter (CPS) to the 'test socket' described by the FSM in preparation for removal next week.

CPS is not connected to anything. I believe I found the three lines that long to be connected to the CPS harness coming from the block.

Anyone with pics of where TDC sensor plugs in?

Can I just splice them or is there a necessary intermediate piece?


...it just never ends.

would the tach amp be missing?

my tach works

85 does not use a tach amp, the EGR computer drives it.

If your tach works, what are you trying to fix?

The fsm engine electrical section is a joke.

I haven't driven the car enough to know of anything 'to fix'

what am I fixing? good question. I think I am preventing though. Threads involving the CPS say little - it must do little.

But it is not connected to anything and I have three bare wires that are cut and dangling behind the driver's headlight... which one goes where?

The plug where the tach amp usually sits is just a port to measure RPM by the mechanics, it has no function during normal driver use.

The pigtail of the amp base should have 3 wires- Brown, green, black.
Brown is ground.
Black is power for the amp and tachometer.
Black/red or green stripe is signal to the tachometer display.

oh.

thank you.

The sensor on the harmonic balancer?

the only wire that goes down to the bottom of the front of the engine?

near the markings for measuring chain stretch and injection timing?

Right, the EGR computer uses the flywheel teeth pickup on top of the bellhousing for the tach on late 84-85 models.

Yes, that is in tact.
