I tried to search it but can't find the answer. How do I get code for my 86 Pickup?

 

Paper clip and TE1 and E1 in the diagnostic box. It should be right beside your fuse box under the hood unless it is an early 86. Then there will be a plug on the drivers side by your coil.

Don't you have a haynes book or something? Time to drop 20 buxx and get one sir.

 

i didnt think about a Haynes book. thanks man

 

here's what the codes mean, if you don't have these yet...
