Can't find the service connector to set ignition timing

Postby racer555 » Sat Jun 27, 2015 3:44 pm

I was going to try and set my ignition timing earlier and could not find to service plug. I bought the car with the 4age swap already done (sr5 to gts) and can't get ahold of the guy I bought it from. I checked throughout the entire engine bay and couldn't find anything that looks like the service connector. Is there a trick to setting the timing without jumping the terminals at the connector?

If you can't find/don't have a diagnostic plug to jump, do this...
1. Get the engine up to normal operating temp.
2. Make sure it is idling at around 850-900 rpm.
3. Hook up your timing light to #1 spark plug lead.
4. Check to see where the notch on the crankshaft pulley is compared
to the scale on the front of the lower timing belt cover. A dab of whiteout
on the notch makes it easier to spot.
5. Set the notch to 16-17 deg BTDC (adjust the distributor if necessary).
6. Put your light away, close the hood, grab a beer... you're done :)

Also you can ground the terminal directly on the Ecu by back probing it, this will achieve the same effect as connecting the te and e1 terminals.
