One member did a EEC-V OBD-II a number of years ago. 08-09 maybe? VERY involved. You need everything, I mean EVERYTHING. Seems he had crank sensor/mounting issues.

Overall there are just too many possible combinations so that's probably why nobody has tackled it, and IMO I don't think it's necessary anyway, there is enough info contained in this forum for anybody to get it done with some specific help from others that have already done it if necessary. The good new is that no matter what EFI truck you have to start with most of the wiring you need for a MAF conversion is already there and it doesn't need to be touched for the most part. The simplest way to go about a conversion is to get a donor SEFI harness and disect it to remove the sequential injector and MAF wiring portions as complete as possible meaning all the way back to the EEC connector, then wrap these up in loom and tape to create a little overlay harness and add that to what's already in your truck. To do that you will need the wiring pinout for whatever PCM you're using, if it's a truck PCM you just have to add the sequential injector and MAF meter wires to the stock connector, but if it's a car PCM(Mustang/CougarTBird) some additional wires have to be moved along with installing the extra injector and MAF wires. The EEC connector comes apart to facilitate moving and adding pins so the hardest part of this is simply gonna be working in the cramped quarters under the hood, but if you minimize the work necessary as I have suggested I don't think this will be so bad. If anybody has any specific questions about this send me a PM, I'll do my best to help you out with your project.
Hi, trying to convert to maf,
95lightning using ECM part# E5TF-12A650-BYA. out of 95f150/Bronco, California emissions w/e4od, I have read alot of forums, and have got at least 4 different answers to the pinout of this Ecm, if you have the correct pinout diagram for this ECM, I really could use it right about now, lol, and also, the correct pinout for a 95lightning would also be of help, really want to get it right the first time, but am loosing hope with all the conflicting info, thankyou.
