DDE on/off problem

anyone have a clue on what might be causing this?

unlock - fades on DDEs

start engine - turns off DDE

im guessing, because the footwell lightning went off so did the DDE?

i did the ECU tap first (wo/ doing the footwell tap) and tested it. the DDEs stayed on after the car was shutdown for a few seconds. then i did the footwell tap.

which wire for ECU just so i can recheck.

any other things i should check?

The ECU tap should be the pink wire. Make sure you really clamp down on the t-tap that is included.

Check a few things:

1. - Is the fuse in blown or incorrectly seated - all the way and actually in the slots, some of the fuse holders are tricky
2. - If you turn the key to the on position, and turn the interior lights on, do the DDE's stay on?
3. - Do you hear/feel a clicking from the relay when you turn the key on (will require an assistant).

If the fuse is blown and a new fuse works - problem solved (same as if its mis-seated)

If the DDE's don't stay on with the interior lights on and the key on, the relay isn't tripping (meaning the ECU tap is good) and there is a problem with the power connection you made (fused wire). Conversly, if the lights stay on (but are off with the interior lights off) you will come to case 3.

If you aren't getting a click from the relay its an issue with the ECU tap, if you are getting a click its an issue with the power wire.

The wiring here isn't very complex - only a certain number of things can actually be wrong, my guess is honestly on something with the power wire.

Hrmm.

so yea it doesnt seem to the pink wire or unless i didnt tap it correctly.

2004 Facelifted coupe, sport package, bixenon. did not need to bake headlights.

at the moment its like this. I took off the ECU tap altogether. The DDEs fade on and off with the interior lights.

being limited with the provided t-taps i bought new taps from radio shack.

sorry just giving out more info about the car. several different DIYs wrote different color wires to tap.

1. which fuse are you talking about? the OEM fusebox in the glovebox or the dde harness one.

2. Yes the DDE's will stay on/off with the interior lights. So basically i think did the footwell tap fine.

3. I will check for this asap. the little box should click right?

using taps for 18-22 guage is correct aye? im using the radioshack onces which isnt like the ones that were provided, should be the same? (i use these taps on my car so i believe they are fine, just checking all corners.)

btw tyler thank you for your help.

Any chance you sell premade DDE harnesses w/ remote kit? finding time to build one, though cheap, requires about a day's worth of time for me which i often do not have.

Its the ECU tap because of number 2.

I was referring to the fuse on the harness.

The 18-22 gauge taps should be fine, I think the wire is a 16 gauge wire so they usually cut a few strands rather than not getting far enough through the insulation.

I can sell the harnesses, but they cost like $40.

Go to walmart or discount auto (or pepboys, but its more there). Look for an auxilary lights wiring harness, APC or pilot are the two brands I've seen. Has white sleeving on the wires comes witha ricey swithc and a 4 pin relay.

Won't use the remote kit but its $10.

These DDEs are actually bought from you, umnitza. I've been asking these questions for my friend.

The wiring for DDEs are 95% the same(or maybe i am stupidly mistaken) so i didnt want to so i didnt feel the need to point out where i got it from.

If that's the case, and they are purchased from us - then definitely listen to your retailer, contact us so we can resolve it.

well could you start by confirming the correct color wire to tap in the ECU area?

Yea still problematic.

so the pink wire was no good, scrap that idea.

we retried the red wire/yellow dots/white stripe which i had originally tapped. It worked for abit now the interior light switch doesnt even turn on the interior lights. So some kinda short is happening.... somewhere.

im going to try and remove the ecu tap and see what happens.

From what it sounds like, the ECU tap was fine in the first place, it was the source wire that wasn't fine. When you started your car, the ECU wire would become hot, flipping the switch inside the relay to use the source wire instead of the footwell lighting tap. Since the source wire wasn't supplying the relay correctly (whether it's a blown fuse or bad connection, i'm not sure), and thus, the DDEs would be off.

source wire? you mean the one that is directly connected to the + terminal?

once we took the ECU tap off, now everything is back to as it was. Cabin lights turn on/off the DDEs.
