Thanks all for your help. Smoking rooster was right, the cable goes through the drain hole of the splash well. Unfortunately the cable connection to the head unit doesnt fit behind the jackplate. I assume I need to raise the jack plate enough for me to pull the cable through. So I tried doing that, loosened the side bolts and went to raise the jack plate and nothing happens. Is this something that seizes up if not used or can I try to “encourage” the plate to move
