I am putting in a relay/isolator to seperate my batteries, but one lead of the relay needs to be connected to the ignition wire. I don't want to tap into the wire behind the head unit because there is very little length left to work with and I already have 2 splices off of it. Where else close to the dash, etc. can I tap into the ignition wire and what color is the wire? It is a 1994 Integra, but it should be the same up to 2001.
Thanks much
PS - It's a 2 door GSR, not that it matters.

 

Just tap it in at the ignition key switch under the dash, plenty of current there.

 

Oh and btw its the black with yello wire.
