Actually, i'm wondering if I've missed something. When the alarm was fitted, we couldn't find a pin switch for the tailgate, and the small light right at the back is on/off only. However, looking at some past posts here, there may be some kind of micro-switch in the rear latch that illuminates the main florescent courtesy light and also the dash warning light. In which case, this could be the culprit? Could anyone confirm whether there is some kind of switch there, and if there is, which wires to look out for?
I'm wondering if this is also related to the fact that the original remote lock/unlock button on the toyota key only worked 5% of the time (I assumed it was the battery, but could the rear tailgate switch have not 'shut')?
Thanks again
