SR to KA dash wiring problem

[ska]

I have a s13 sr20det blacktop, and there are 3 black ground wires on the SR harness(circled in red) and only 1 ground wire on the KA plug(circled in blue). How do I know which ones to connect? or do I connect all 3 wires into the 1 wire on the KA plug?

I would connect the one wire to all three, if you want to be OCD about it you could even add another wire and ground it to the chassis also.

@Sileighty_85

that link doesn't tell me anything other than "may be more than 1" ground wire. It does not tell me if I should join them all or not, which is my question.

SR Wire Color .......................KA Wire Color..................... Function
