I am attempting to fabricate a ISC motor pig tail for the Cadillac 4.9. Do anybody know what the length of the cable is supposed to be? I've tried eye balling it and I can't get it to fit quite right. I don't have the original to measure. Also, are there new ones available anywhere?

Both upper and lower have the middle fastener.

The fuel filter should be attached to the fuel line near the gas tank. Although it is possible to change the fuel filter with a screw driver, a quick disconnect tool makes it easier. You can pick one up at pretty much any parts store. https://www.amazon.com/dp/B0195XBPPQ/ https://www.harborfreight.com/3-piece-quick-disconnect-tool-set-38732.html

I am trying to remove the front door hinge. There is a round fastener between the two 15 mm bolts. What is it and how do I remove it?

I adjusted the TPS using a multimeter and that seems to have fixed it for now.

Thank you for the helpful replies

My 4.9 Seville idles high on start up, around 2,000rpm. It stays that way for about 3-4 min before settling down to around 800-1,000 rpm. Once the car is warmed up, I can shut it off and restart it and the car idles normally. I replaced the ISC with a spare one and did the idle learn procedure, and it does not seem to make any difference. I am showing codes E030 and E055. Some possible things I am thinking about checking is the timing and TPS. The problem is I don't know how to check if the TPS is OK or not. Is there anything else I am missing?

Sometimes acid bubbling or leaking out of the top of the battery is a sign of the alternator overcharging. That may have been what caused the alternator to burn.

Does anybody know of a good place to get a cluster rebuild? I have a cluster that intermittently stops working. The lights on the display goes off, the speedometer and tachometer stops working and the climate control defaults to 75 degrees. The lights in the radio display also stop working, but the radio still works. Fuel gauge sometimes gives inaccurate readings, although that may be a separate problem. Some of the lights behind buttons are burned out.

Does anybody know how to replace the door hinge detent roller and the pin holding it in on 90s Sevilles and Devilles?
