I have a 94 S-10 blazer that has the 4.3 and had an automatic transmission. I'm putting this into a 94 Toyota pickup that has been completely gutted (Just a cab and frame). I'm putting a th350 behind the 4.3, I'm going to use the fuel injection setup, but was wondering if i have to obtain a different ECM? Will I need a Manual trans ECM to get the truck to run correctly because of the VSS? Thanks in advance for the help

you should be able to use the ECM from the donor vehicle (blazer). You can have this ECM programmed for a manual instead of automatic transmission. PCMAMERICA.com offers services for programming and wiring harness mods. They also sell a DIY type wiring harness kit to convert the wiring harness to a stand alone type setup. You can also check ebay for their listings.
