HELP! TPI, what did I buy? Etc.

Hi. Many places I looked said I would find answers from you guys. This, and future questions may have already been answered, but I'm new and haven't discovered the answers. A little background- I'm an old hot rodder who has worked on carb cars a loooonng time, but I wanted to jump into fuel injection. So i went out and found a TPI complete+ setup on Craigslist- manifold, fuel pump, 2 different wiring harnesses, and 2 different ECMs (along with associated sensors). I got this because: 1- I didn't want the TBI hiding under a stock-ish air cleaner look, 2- I couldn't afford the Hilborn look, and 3- this was cheap & I liked the look. I plan on installing this in a 1928 Ford Model A coupe. Now let the questions begin. But first-

How do I move pix from my album to this thread?

Re: HELP! TPI, what did I buy? Etc.

Trying this by loading from my iPad. ECM- what year is it? MAF or SD? Info about the company on label? Any guesses on chip? 1st pic, bottom view. 2nd pic, connectors.

Re: HELP! TPI, what did I buy? Etc.

Thanks for the replies. Now on to the next questions..... Do I have to re-burn the prom cuz it’s for a 383 and not a 350? Is there a place that can scan it to see what’s what? I assume that because it says off road that the vats has been disabled? Finally, what is the thing on the bottom and what does it do?

Re: HELP! TPI, what did I buy? Etc.

It can be read but it would be best to start over with a tune. It might have egr air pump disabled. The other piece is a relay.

Re: HELP! TPI, what did I buy? Etc.

To elaborate, a 383 uses way larger injectors, the ve table will be to far off for a 350. Same thing with a unknown timing table. It’s better to start over . The relay could of been a fan or fuel pump relay.

Re: HELP! TPI, what did I buy? Etc.

Thanks for all the replies guys.... now on to the next phase. As I said before a wiring harness came with it. That’s the long shot pic. There are a couple of connectors that I am unsure of... The connector in the 2nd goes to...? The connector in the 3rd pic goes to...? And there are individual connectors. Any ideas? I guess this was a no frills wiring harness for a stand alone install?
