Hello Fellow XK8ers,

I recently had to remove the throttle body on my 1997 XK8 to address a leak in the coolant hose underneath. In doing so, as i tried to remove the electrical connector to the TPS, the connector basically disintegrated under my grip. After replacing the connector, the car ran extremely poorly. Every light on the dash was on. My guess is that I got one or more of the wires mixed up upon reassembly of the connector.

Could someone please confirm the order of the wires from top to bottom being:

1. Blue with white dot
2. Solid Blue
3. Green
4. Black

Many thanks in advance!!!

According to electrical guide your order seems right but l don't know which end is pin 1.
Book says pin 1=black, 2=green, 3=blue, and 4= blue/white.

 

Ok just looked. This is from 1998, but it may help.
Pin 1. BG black green
Pin2. G green
Pin 3. U blue
Pin 4. UW blue white. See diagram #2. Pin4's UW is connected to the UW wire into pin 4 of the Pedal position's 5 Pin connector nearby.

From my car, I can confirm, from top to bottom:

Blue (I can't see the white tracer)
Blue
Green
Black/Green tracer

corresponding to pins 4 through 1 on the EG

The 97 EG shows the same as the 98 other than the disclaimer for very early cars (<003300 VIN)

So it looks as if you're good.

 

I was kind of hoping I got the wires crossed. Any ideas as to why it's running so crappy? I must have missed something big.

 

on the engine, from top to bottom,

Blue/white
Blue
Green
Black?

 

l would start at that plug even though pins seem correct, maybe something else there is compromised.
If l read the diagram correctly probing at the plug should give readings of black-ground, green-half volts idle, blue-half volts idle, blue/white-5 volts
if you get anything like that you could assume connections at that plug are all good.

 

Thank you!

 

l should add, the half volts is point five volts. I thought the (.) in .5 might get missed.
