Up for auction is an SCT 4 bank chip for 87-93 ford mustangs. Part number through SCT is 6600. It may work for other years, but do your research. The unit was removed from a previous project of mine (1990 fox with 331/nitrous). It worked flawlessly, without any issue. I do not have the cable anymore, to my knowledge. If it is found by end of auction, I will gladly include it. 

Happy bidding, feel free to ask any questions!
