I read the PCM has three 32 pin plug ins, on a 1997 XJ.

I do not know which of the three 32 pin plugs is "A", or "B", or "C".

Which one is closer to the firewall?

I have been trying to trace a possible ground or bad connection on

the "A7" pin, but could not find which plug is "A",

Thanks for info, ..

The one closest to firewall is c and the one closest to the front grille is a

It looks as the pin A7 I am looking for is in PCM - C1,

the 32 pin closes to the firewall.

Thanks everyone for your help.....

This morning doing a little more testing.

I put a voltmeter on the gray wire at the coil, and disconnected each of

the three 32 pin plugins. The plugin nearer to the front was the only one I

got a change in reading from, when connecting and disconnecting.

I believe the front 32 pin has the A7 I am looking for.
