I disconnect the battery ground, take care in pulling the plastic slide clips out at the wiring harness before trying to pull the harness plugs free. The slides will pull out a 1/4 in. or so, and then you can use a screw driver , etc. to carefully pull the slide clips all the way out, and the harness will be free. Do a search, as there is a good LT post with photos on this.
I'm also thinking of getting an ECU flash, but am worried about the electricals.
What is the correct way of disconnecting the battery and stuff?
I remember reading that if the battery dies, bad things happen, but wouldnt disconnecting it do the same thing? That makes no sense to me as how would you go ahead and replace the battery as a normal piece of maintenance?
thanks. sorry for being a newb. I'm just super paranoid about everything when it comes to my lotus
