I would double check the paper clip trick, are you sure your jumping the correct ports?

I think he's saying that he has two different situations, the brake light won't go out since he converted to the vacuum set-up.
The 2nd problem is using a paper clip to jump the box under the dash to retrieve the codes on the SES light that is on in his dash, doesn't do anything.

Shmed,
Like Gary mentioned, the emergency brake isn't on by chance? May want to check the switch down there is ok.

Post by: shmed on September 09 2012, 03:41:20 PM: YES steve once again you guessed it.
i went out an checked it was off altogether..
as for the ses light... i changed the ecm back to the stock unit an all is good...so im gonna assume the ecm was faulty...
