Does any one have the pinout for this model specifically? Computer Serv. No. is 16263494.

If I cant get this dang thing to work Im just gonna have to convert to a 0411 pcm and give that a shot. I have searched and can't find this specific wiring anywhere.. If someone has an account with alldata can you pull the schematics off it for me please. Thanks
