location of eec data connector
Hi
I have a 2001 F150 5.4L with a problem which needs attention. Before I go down to Autozone to ask them to borrow their reader, where can I find the EEC data connector on my truck?
Thanks a million,

Thanks loads,
They handed me the reader and told me how to use it. (saved me $80) read was:C0308 missfire. I don't know the code but based on what Iv'e been reading here 08 designates #8 cyl.
It's time for plugs anyway and I will be testing the #8 coil just out of curriosity. I got a replacement while I was there.
Thanks again.

There are several precautions that you should be aware of when changing plugs on these engines. Read the thread that is stickied at the top of this forum about changing spark plugs to learn everything that you ever wanted to know. This is NOT an engine to haphazardly slam plugs into. The threads can be ruined costing you BIG bucks.
Make sure you only remove the plugs while the engine is cold, put on a LIGHT coat of copper based anti sieze and torque them no more than 20 ft/lbs. I only torque to 15.
When you change plugs if you don't see alot of evidence of problems in the number 8 hole, or see that the coil has been very wet, swap it with another cylinder when you put it back together. THEN if it sets a code again, see if the misfire detected stayed on number 8 or follows the coil.
If THEN you start up the engine and still misses wait til it sets a misfire code again and that will tell you which coil to change.
Good luck,
Doc
