I checked 3 Rams and 1 Ramcharger at the local yard yesterday, years ranged from 87-93. NONE were the same as mine. They all had a single molded plug and different terminal layout, and mounted right in the cowl. Mine mounts on top the heater box. I also checked a couple mid 80s Fifth Aves, also different. The only car at that yard that might have one the same as mine was an 80 Volare. I would've had to disassemble half the dash to get to it and I didn't bring enough tools with me to do so.
