As the title says, I have an extended boomslang harness for an MSM for sale. Since this is a straight through harness I would imagine this would work for all 01-05 miata but don't know for sure. This extension is long enough to mount the ecu in the glove box or passenger airbag area. I used it long enough to get my car running and find someone small enough to lay in the floor and mount the ecu up in the standard area. Worked great for me. Looking for SOLD shipped. Any questions, let me know.

SOLD
