Hi. I'm trying to install an X-Charge ( http://www.x-eng.co.uk/X-Charge.asp
) split charge system on my 110. It's an '86 110 with a 200tdi retrofit. I've never done anything like this before and I'm sort of stuck.
There's a wire that the instructions say goes from the alternator to the battery charge indicator lamp on the dash. I'm supposed to splice into this and run that wire to the relay that came with the X-Charge. I found the wire, but I'm not sure if the recommended procedure is to splice into it from the engine bay, or follow it into the cab and do it from there.
It seems like it would be easier to splice into a wire that's already in the cabin, as then I don't have to figure out how to get a wire through the bulkhead, and worry about it melting on something or getting shredded somehow. But I just have NO IDEA which wire in the cabin would work, or even how to figure that out!
Also, am I better connecting my negative battery terminals together, or separately grounding each battery? I thought separately grounding each would be better but the instructions say to connect them together.
Thank you very very much,
