Woody, the electrical schematic that you need is on Page 97.55. The ignition control module is on the left hand (drivers side) of engine compartment just ahead of the idle stabilizer and the coil. It looks like a very large transistor mounted on a heat sink. It has a seven-wire connector leading into it. Trick here is to find which pin of the connector to the ECU is pin 1. To do this, remove the connector from the ECU and the connector from the ignition control module. Set your ohm meter to the highest setting (like x 1Meg). Put one probe on pin 7 of the connector to the ignition control module and then find the pin of the connector to the ECU that gives essentially 0 resistance. The one that does so will be pin 1. As I remember, it is the top right hand one as you look at the connector. Pin 25 (opposite row at the bottom) should give 0 resistance to chassis ground. Pin 2 should give 0 resistance when checked against one of the two pins on the connector to Temp Sensor 2. Hope this helps.

Dear John, Thanks for your rapid reply. Can you bear with me just a bit more and lead me further down the path towards enlightenment? > Find the appropriate > electrical schematic. Can you give me a Bentley page reference? > Disconnect connector from ECU along with connectors > from Temp Sensor II and Ignition Control module (pinouts are marked on that > connector). What is the "Ignition Control Module?" Does it go by another name as well? > I used ohm meter to confirm connection and the double checked by > ohming out pin to Temp Sensor II Can you explain exactly how to do this? Does "confirm connection" mean that your ohm meter reads zero or close to zero ohms? Where exactly did you place your meter probes? Does "ohming out" mean doing the same thing, that is, checking for resistance? I don't see how you are carrying out two tests here : confirm connection" and "ohming out pin to Temp sensor 2." Thanks a lot. As you can see, I am real beginner with this stuff, but I am the proud owner of a new Craftsman multi-meter (Model 82028 -- BTW, are they any good?) and I am determined to master at least the basics and get my engine running smoothly and efficiently. |
