after putting my 4ag in i want to wire up a check engine light, i got the ecu wiring diagram, am just wondering if there is a unused light on the ke70 dash or if i can just simply wire in a loose lamp at all?

hey mate, no extra lights unfortunately.

 

i just used one of the old radio volume control knob holes (up on the left) and found a globe bezel that fit in. i think i had to file it slightly.

 

if your keen you can put a new light inside the dash though. may be a bit of a pain, but it would look good.

how do you wire it up though?just simply the wire from the ecu and then to earth?

 

i was thinking of putting a polished ali plate over the area where old radio went then putting a small light in there along with any other relevant extras.

On a bigport ecu from memory its the thin gauge red wire. i to wouldn't mind know how to do this. is the wire a negative trigger or positive?

yep i got mine sorted last night. I looked at this pin out diagram http://www.club4ag.com/technical_main.htm#...0and%20Learning

and realised its the ground wire, so just wire the light up to a +12V and then the other side of the light to the thin red wire. boom presto it works :jamie:

 

Ke70Dave confirmed that it is wired like this today too.

EDIT: double post.
