E-Fan Harness - Blue Wire?

[sparg93]

I have a BB Harness and I was wondering how to install the Blue42 wire into the PCM?

I've never touched the computer before, so I was hoping someone had pics or could provide me with details how to install...on my harness it's the blue wire with the metal pin at the end.

Is this for the '99 in your sig? Do you have a pic of your PCM? I did this install on my 03, but I don't want to assume that your earlier model is the same.

yes, that's correct...for my '99 (i'm altering the harness to work with my Mark VIII e-fan fan).

I guess I just don't know what to do with the blue pin on the harness and how to install it.

anybody?

even if the computers are different, how do I physically insert this blue pin into the computer? Am i sticking it into some form of a port, tapping it to another wire...?

Any help would be greatly appreciate

take the computer off the holder, take the 10mm bolt that holds the clip and pull out. you have to take the plug out of the 42 pin hole and insert wire. be sure it seats all the way in and remove the clear blue plastic trim ring to get in all the way. thats the way i did it, took about 30 mins to install my efans
