However there is 5th wire, a ground, from the DirecLink that needs to be connected to a ground on the Lexus. Apparently the Lexus/Toyota specific connector does not include the ground.
I have attached a photo of the Lexus specific wiring harness showing the connector to the Lexus on the left and the connector to the DirecLink on the right. Coming out from the connector to the DirecLink is a 5th white wire that should be connected to a ground on the Lexus. My question is where should I connect the white ground wire on the Lexus?
