can someone take a picture of the diagnosis plug that is next to the fuse box a picture before u open the diag cover would help so i can find it i have the 2 plugs on the drivers side also

 

On the 85 4Runners, one of those two plugs on the drivers side is the diagnostic plug.
check 4crawlers web site, it will help you alot.

 

the diagnosis plug so i can pull my engine codes i guess im not lookin hard enough so can u send a pic of the diagnosis plug

 

ok marlincrawler says its the big plug but i do not know which inputs to jump can u help me and take a picture to show me

 

on the plugs i dont know which whole on the adapter it goes in can u help

 

Well, there are only two sockets on the diagnostic plug so just make up a jumper wire to fit into both at the same time to connect them together:

what does the dianostic plug look like before opening it can u send me a picture

 

is it the small plug on the driver side fender well cuz that one has only 2 ports

 

If you read the information on the page I posted, you'll find the answer.

Hints:
1. It is the one circled in light blue
2. It is round
3. It is the one with 2 wires (the other round connectors have 1 wire and 3 wires)
