Hello! I just received a cruise control amp from a wrecked '83 300D (thanks Bernie!). I looked in Fastlane, and Fastlane gives the same part number for both '83 and '85. The pin count and arrangement are the same between the '83 box and my box. However, the box is physically a little bit (maybe a half inch) shorter and has different numbers on the outside.

I'm just wondering, if I hook this box up to my system and try to use it, do I run the risk of damaging the actuator or anything else?

Thanks in advance!
