lock up switch.
i have 1996 ranger 2.3 and 4r44e trans i think.
will this info below work on mine?????????
how do i find pin 53???????
The lock up TC circuit is a ground switching system. The ECU grounds the circuit to control the operation of the TC. So in order to install a switch to force lockup all you have to do is hook up a grounding circuit.
1) Locate pin #53 on the ECU. They are numbered on the ECU.
2) Tapp into the pin #53 wire in the engine management harness.
3) Run a wire from the pin #53 wire to a switch, then from the other side of the switch to a good ground. I ran mine to the negative battery terminal.
Note: Haynes manual says the wire is Pink and Yellow but mine is Orange. You can verify the wire color by looking at the TC plug on the transmission.
Now you can control lock up. When the switch is in the on position the lock will stay locked up regardless of engine load as long as the transmission is in 3rd or OD.
When the switch is in the off position the lock up will operated as it always did.
Note: There is no lock up in first or second. The valve body overrides it in those ranges. Also remember to turn the switch off when coming to a stop or the engine will lug down until the transmission drops out of 3rd gear.
