Got round to doing my boot release today!!! Used 2 relays (one std, one CDL 6 pin relay) but I didnt use a solonoid I used a CDL motor (cheaper and alot less powerful) The 6 pin relay means if I leave the wiper switched on nothing burns out.
Nearly finished filling the hole in the boot for the button too, didnt get out in time this morning to pick up my bigger anchors though
Piccys on thread, took loads of wiring!
