On the pas side, above where the passenger's feet would be you'll find a single wire that can be disconnected. It's an in-line type connector. Disconnect that wire, start truck and check timing. Reset as necessary. Reconnect that wire THEN pull both ECM fuses (on the fuse panel) for 30 secs or so. Reinstall fuses and you're good to go. No wires in the engine bay are disconnected.

Don't know of another place to disconnect it but it's not hard to find at all. Just pull down the carpet a little on the passenger side and it should be just right there below the dash.

i know where to disconnest the wire by the pass side. but i m wandering where that same wire goes in to the engine bay because i have that same wire disconnected right now and need to know where to plug it in at

Huh? Can you explain that a little more? There isn't a quick connect in the engine bay for just that one wire. Under the passenger side carpet is the only place. And for your other question, no, it doesn't affect the speedometer.

it may be a test point somewhere on the harness :2cents:

If it's right behind the dist then it might be the fuel pump test term. Don't know the color code on that wire though.

Re: brown wire for igniton

The wire by the 12v block behind the dist is for the fuel pump. If you touch that wire to the 12v block(terminal on firewall with the red wires on it) it will turn on the Fuel pump. There should be a tan wire (mine has a black stripe) under the carpet or tust above the plastic cover under the dash. It has a black disconect plug.

"The ESC Electronic Spark Timing "tan wire with a black stripe" that everyone can't find when attempting to set their timing (s-series). Wire is under the carpet on the passenger side below the heater box. It is disconnected to set the timing, then reconnected."

"Applying 12 volts to fuel pump test connector to troubleshoot fuel pump or set fuel pressure with vacuum line still connected and motor off (note fuse for safety)."

If you are having issues with your speedo, the first place to check is your brake fuse to see if it's blown...
