Need a PCM connector pin location diagram.

Need a PCM connector pin location diagram for a 93 XJ, 4.0. The FSM I downloaded did not have one, and I have been unsucessful searching the forum for a link to a diagram. Any help would be greatly appreciated.

As far as I know, it's the same on a 95, so here's what the 95 FSM shows...

Ok, here we go. You're looking at the connector on the harness, not the PCM itself. There are three rows of pins, or actually cavities, and they are numbered starting at the top left. Top row goes 1 to 20. Middle row goes 21 to 40, and bottom row 41 to 60. All three rows are interrupted in the middle by the hold-down bolt.

The list is as follows:
1-MAP sensor signal
2-engine coolant temp signal
3-fused B+
4-sensor ground
5-ground
6- 5-volt supply
7-8-volt supply
8- blank
9-ign. switch output (run/start)
10-power steering switch sense
11ground
12-ground
13,14,15,16 - injectors 4,3,2,1
17 and 18 blank
19 ignl coil #1 driver
20-generator field driver
21 intake air temp sensor signal
22-Throttle pos. sensor signal
23- blank
24 -crankshaft pos. sensor signal
25-SCI transmit
26-CCD Bus + (4.0 auto only)
27-a/c cycling switch sense
28-a/c pressure switch output
29-stop lamp switch sense
30-park/netural pos. switch sense
31-radiator fan relay control (4.0 only)
32-malfunction indicator lamp driver
33-veh., speed control vacuum solenoid control
34-a/c compressor clutch relay control
35-blank
36-generator lamp driver
37-blank
38-injector #5 driver (4.0 only)
39-Idle air control motor #1 driver
40- Idle air control motor #3 driver
41- heated oxygen sensor signal
42-blank
43-tachometer signal
44-camshaft position sensor signal
45-SCI receive
46-CCD bus (-) 4.0 auto only
47 - veh speed sensor signal
48-veh speed control coast/set switch sense
49-veh speed control on/off switch sense
50-""" resume switch sense
51-automatic shut down relay control
52-blank
53-veh speed control vent solenoid control
54-up-shift lamp driver (manual trans)
55-blank
56-blank
57-Automatic shutdown relay output
58-injector #6 driver (4.0 only)
59-Idle air control #4 driver
60-Idle air control #2 driver

Rasper, Just sent a PM to you.

Thanks to both for the replies, these will both definately help. I'll post up if I learn anything worth sharing.

Nate´s site where you downloaded your partial 93 FXM was shut down by Jeep.
Google is not your friend, sharing can cause problems. Jeep´s (or there sub contractors) obsesive protection, of what should be free information sucks. Makes Jeep seem petty, cheap and bloodsucking.
They spend millions a year to promote there product, then alianate customers by harassing them, when they share, service and maintenance information.
