M3 firewall harness/cover re:m20 diagnostic port and relays

[tinkerputzer]

I may wrap some of it just to prevent chafing and contain all of the extra wiring.

The harness under the cover isnt wrapped

[tinkerputzer]

I'll heat shrink the splices i make, but will need to re-wrap the entire harness due relocating the relays and diagnostic plug.

[nando]

Yeah, that stuff is good. I use shrink wrap where possible though.

[tinkerputzer]

Thanks! Wanted to make sure i wasn't the only one seeing this encase it was due to a larger problem.

What type of tape are you guys using to wrap the harness? I've got some scotch super 33+ vinyl electrical tape i was hoping to use. The packaging says it is good to 105* C. Will that be ok in the engine bay?

[nando]

yes but it doesn't matter. the plastic cover isn't going to hurt the engine. :p

[tinkerputzer]

When it was all said and done was the cover still slightly touching? I had to trim the tray just to get the cover on as it was so tight between it and the intake. I'm wondering if it will be ok if it i lightly touching the intake.

[nando]

yes, it needs to be trimmed.

[tinkerputzer]

Doing this right now. Did the cover assy end up touching the intake manifold (m20)?

Nice find. Items 21, 22, 23, 24 it is then. Any recommended clips or fasteners to go with them?

nope but a hack saw or dremel will help you install it.
you need to remove some of the studs on the piece of firewall that bolts to cover the blower motor.
put you new m3 piece and mock it up on the firewall and figure out which ones you need to keep.
you for sure need one on far left side(passenger side) of the fire wall.

[nando]

buy the passenger side cover from an M3. the 318is one (#15) doesn't fully cover.

[tinkerputzer]

Is there thread somewhere with a list of parts required to do this.

1,2,3, and 15 look like the basic items you would want. Are there any others?
