Rear Permanent and Ignition Lives.....

Quick one, as i understand there is the permanent purple and then the ignition green/white live to the rear wiper motor, but can I take a feed from each of these into a A/B blue sea fuse board to feed other circuits? Or is there a limit to what these can handle? I have the rear seat heaters, the alpine sub and 2 lazer spots to supply.
Thanks Andy

mcma, the loads you want to add seems like a lot of amps to add to an existing wire.

I'd use the ign live that's already there to switch a relay that feeds directly from the battery.

The permanent live to the towing electrics is fused at 20amps, from memory, and the feed to the rear wiper will be a lot less. I can't imagine that either would be up to the job of seat heaters and a sub. It'd be far better to run a dedicated power supply for that kit. Darren

Yea, its was early to be thinking about electrics

I think a heavy live from the battery into an ignition sense module and then feed A & B with those would be best. Andy

Why bother with the ignition sense, use the rear wiper ignition feed as the trigger.
