Window lift relay circuit
is live on both sides at rest.
This schematic requires that you mount 8 relays (2 each) in the A post
and B Posts and cut into the motor control wires. You will also need to
Up Rest Down
run a brown wire from the terminal post to each relay and we would recommend
Pins 1&3 - Pins 1&3 + Pins 1&3 +
that this goes via a thermal breaker ether additional or using the one from
Pins 2&6 + Pins 2&6 + Pins 2&6 -
the existing circuit, remembering to include a fuse to the + side of the switches.

Please insure that a copy of this circuit is inserted into your cars literature

and that you attach a label to the switch harness so that the next owner or
garage know that this car is non standard.
As to why Jaguar decided to wire this for constant positive! Its any

ones guess, one short and its game over.

This schematic requires a little more work and involves swapping
the Positive and Negative terminals on the back of the switch.

This results in the relays and motors lying at negative when to

This schematic uses special relays that requires only 4 packs instead of
the eight required in the other two diagrams and greatly reduces the amount

of wiring required. Please note that this is wired for negative at rest but is
Pins 1&3 - Pins 1&3 + Pins 1&3 +
essentially the same for positive at rest as only the relay part of the circuit
