Need help on 87 GM Buick GN ESC pin-out...

[Iestyn Guest]

Hello All -

Do you know what the pin-out assignment should be for the 87 GN ESC module?
I'm building up a new system using the Felpro SEFI8LO system - It requires a
standard GM ESC - I wasn't sure what to buy from the local GM dealer, so I
got an 87 Buick GN Module.

Now I have the module, but have no idea what pins to wire to the ECM, knock
sensor, Power and GND etc..  The only thing I do know is that the one wire
to
the ECM is kept 'high' until knock is detected, and then pulled 'low' to
ground to retard timing for the duration of the knock. - Most auto books
show just a color coded wiring harness for 4 wires.  I don't have the
harness and this ESC module has 5 pins!!

Please help if you know.

Kind regards.

Iestyn.
