dash connector ground on wiring harness question

[chuckyD1]

from the sr20 wiring harness theres 3 black ground wires that go to the dash connector & on the ka dash connector theres only 1 black ground wire .... do i choose 1 n connect it ?? or do i splice in all 3 ?? any1 could give a hand would be great ! thanks

[chuckyD1]

could still use a answer on that ground situation if any1 has a answer !! if not ima probly just connect 1 n tape the others off to the side !!

what did you do finally ? I have also the same problem.

The ground wire on the US side goes to the consult port.

So I can wire all the same colors and my consult port will work ?

btw, it's a sr20det into a s13 ka24de with a/c (not working) and fully loaded.

You can wire them all together. But the consult port will not work without the tx, rx, and clk wires being connected (the gray ones).

Ok thank you for theses precious informations.

That's why nobody connect them I suppose.

I'm doing my wiring this week-end. I hope everything is going to be fine. I'm using the FRsport diagram.
