1swiftastro

Hello, I am new to this forum. I just bought a 1995 Astro Van. My cousin and I was looking it over, and he stated it looked like some wiring connectors did not belong or the harness might have been replaced under the hood. Well my trip to the junk yard verified that the plug he was refering to was for the cruise control unit above the battery. My van came with int. wipers, but did not have cruise from the factory. So I am assuming all the wiring is there for cruise? I found a '95 astro at the junk yard that had int wipers, cruise and tilt wheel. My question is what all is required to fit cruise on this vehicle? I bought the tilt column and the cruise unit. I'm thinking at the least I will have to add a light to the instrument cluster for the cruise indicator? Thanks for all the help in advance!
