None of the places around me have an OBD1 reader for rent/borrow and dealers want an hour of labor just to bring it into the bay. I also want to get one just to be more self-sufficient.

Is there any preferred kind of reader for the IDI trucks? I was looking at the Innova 3145 with the 3149 cable. Any opinions?

I know I can jump the wires, count blinks, etc. but I have specific readers for all of my other stuff and want one for the 250. To me, $50 for the cord and reader is short money for a lifetime of service. Any other recommendations?

Thanks in advance.

ETA: 1991 F250, E4OD, stock.

 

You only need a code reader if you have the E4OD transmission. In that case the 3145 will work fine.
Otherwise there is no computer/ECM in an IDI truck.

 

The expensive snap on one wouldn't read my tranny codes at my father in laws shop but the innova at oriellys would
