I just bought used off e-bay a hypertech power module for my 1994 4.0L auto 4x4 ranger. It was supposed to have the instructions with it, it doesn't. My question is where is the computer service port located for the chip to plug into? Everything I have read said under the hood drivers side fender well. I haven't seen any such port for this module to plug into. I am sure some one else here as added one of these. Can you tell me where it is and what I am looking for? Thanks!

 

94 is OBDI still...do you have a picture of the plug on the programmer...im willing to bet its an OBDII plug

 

I can take a picture of it if you like. The box says for 1994 4.0L with auto

 

^huh?

 

I fixed my previous comment.....I was cleaning my keyboard with this open and hit enter on accident so you got just random letters! Sorry about that! lol

Lower right side of the page is what I bought.....

 

ah i see haha...are you sure the connector isnt under the dash

 

I didn't find a connector under the dash unless its hidden out of site somewhere. The only instructions I got with it were the ones for cleaning the connectors port itself, in the picture it looks like it plugs directly into the computer, but I have never seen an auxiliary port on a ford ecm just the main that the under hood harness plugs in to. I am also thinking those are generic instructions for all power modules.

 

I found the instructions....I have to pull the computer out of it.....the service port IS on the back of the ecm.....cold....windy.....snowing here....seems like a job for another day....lol
