    Masi 16v underhood harness questions

    Attachment 54352Attachment 54353Attachment 54354Attachment 54355I started working on Masi 16v under hood (SMEC) harness into my Shelby Lancer today. Right away I notice there appears to be a large "sub harness" attached to the under hood harness that is unlike anything I have ever seen before. It is attached to the main harness with zip ties up along the firewall edge for the most part. It has various connectors on both ends, a fuse/relay box, and additional firewall grommet for more wiring and another large connector. It appears to not have any circuits going between it and the main harness and is only held to the main harness with zip ties. Is this for the Maserati TC ABS system and can I just delete it for this swap? I hope so because it would get rid of a lot of unneeded bulk.

    I'm sure I'll have more questions soon, but this is the first 'problem' I ran into.

    In the pics, if you use the main 50-pin bulkhead plug as a reference, you can see the additional sub-harness attached along the firewall run with some wiring/connectors that come out near the windshield washer connectors, and some additional plugs, relay/fuse box, and 2nd firewall grommet near the passenger side strut tower.

    Sh!t can it, it's for the Teves Brake system... If you look in said overlay fuse block, I'll bet that youll find the 25 amp fuse is heat warped. #1 reason TC Masi brake systems stop working is that fuse...

    Just cut out the Masi TC 16v Teves ABS wiring from the under hood harness. I ---- you not that was like 1/3 of the harness bulk and eliminated a lot of unneeded stuff. Eliminating this entailed cutting about 4-5 zip ties and it is out of the picture.

    Teves ABS wiring on the left; the rest of the under hood harness on the right...

    Re: Masi 16v underhood harness questions

    Just curious, can you pop the fuse box open and look at the 25 amp? I can't recall the story of your donor drivetrain, from who where when...

    Will check those fuses tonight. IIRC there were 3 fuse slots and two 30 amp green fuses installed. Everything I'm using for the Masi 16v swap into my SL came from Mark C (sy2206)
