OK I've had my 240 for 2 months now and I just did a gasket and seal refresh and she's running pretty well as far as idling and cooling. However my problem at hand is that for some odd reason the previous owner decided to hack off the throttle position switch connector which from what I read in the FSM controls Fuel at WOT. I looked in the Wire diagram but I only found the Throttle position sensor connector which was listed as F25 but that's not what I'm looking for. I'm Looking for F24 since I need to some how rewire it so I can go WOT. Right now it revs fine except when its in wot it bogs so much that I can't bare to keep it WOT for a seconds or 2. I did locate a connector on a car at the junk yard but the harness was missing I did however grab it so all i need to do is wire it in. Please help Here is a pic of what I'm looking for.

Can someone at least tell me the page and chapter of the fsm? My search feature on adobe is being a gay and it won't search through the page only the bookmarks.

is that the same as throttle valve switch because that is for automatic transmission.

the wiring diagram in tutorial link is pretty exhaustive as far as including everything.

I didn't find anything other than how to adjust the TPS in that tutorial link. I need some sort of ecu pinout or something so i can runs some new wires to the sensor. I say this because I unwrapped the entire engine bay harness and I could not find any cut wires or any that were the same colors as the ones on the pig tail I have.

all the wiring for throttle position sensor is in the above link. if there was a switch for manual, it would be in that wiring diagram.

thank you good sir. This is what I'm lookin for. Throttle valve switch. I guess they named it diff on the schematic. Can you point me in the right direction as to how I would go about wiring it up.

You cant hook it up unless you have automatic transmission. Just ignore it.The wiring for the throttle position"sensor" is in the wiring diagram in previous post.
