Not sure if this is a common sense thing or not in the community but I couldn't find any write-ups on it. Basically the passive restraint stuff on my car was removed in favor of s14 seatbelts and seats. I also added in the s13 silvia interior pieces to complete the ensemble. Immediately after this conversion I noticed my door switches wouldn't shut my dome light off and the seatbelt light on the dash wouldn't do anything when my belt was buckled. I realize this seems petty but there are those of us who want everything working correctly when we convert something. I know not everyone's car had this issue after removing the passive restraints and most of you just ignored it. I'm working with an 89 coupe in this instance.

I chased the wiring down and found two very simple solutions for both of these issues.

First, the door pins not shutting off the dome light. If you pull back the plastic underneath where the s14 seatbelt bolts to the s13 b pillar on the driver's side you will see the back side of your door pin switch. You will see three wires. You are going to want to cut and splice two of them together as in the following picture...

Next, the seatbelt light on the gauge cluster not doing anything when your seatbelt is buckled. The first thing you need to do is make sure your seatbelt buckle sensor is plugged in to the harness under the driver's seat. You'll want to remove the arm rest and locate the harnesses that your passive seatbelt system control unit was plugged into. Find the blue w/ red stripe wire and splice it to the yellow with green stripe wire. You can pretty much get rid of the rest of the wires except for the lighter, ebrake, and ashtray light wires. See pictures below...

Congrats, you're done. Too easy.
