I purchased an unused JB4 Stage 2 from a friend, come to find out it is not the correct harness for my car. I require a Type B, this is a Type A. The tune has never been used. Comes with the keychain, and printed instructions. No packaging. I'll even throw in a 6" JB4 Stage 2 vinyl graphic of your color choice. This is for the N55 engine, it has three connectors (no flex fuel, I believe). Shipping will be flat rate USPS if you are not local to St Clair Shores, Michigan. $530 new, get it for $100 off. Can send pics if you need.
SOLD, THANK YOU!
