I replaced the original radio in my vp and used a wiring harness so no wires were cut but now my aerial wont go up on the radio can put up but it comes straight down. Any ideas.

What's going on is you are only getting power until its fully out then the power switchers off then it come down, you going to have to wire it via the amp pre out on the stereo so it stays active power until the unit shuts off. Depending on how many wires coming from the antenna and how its controlled usually the factory unit with the option up and down positions have more wires you need to work out which wire is the activate and use that, his a diagram using 2 relays, it be far easer just to replace it with a fully Automatic.
