Hello one and all. Just bought a 95 ls400. Well I lost the key first night it was home. So I went a bought an ignition for the net and it turned out the it only has six wire connector on the main plug but the older ignition has seven wire plug can anyone tell me how I can wire this up. Or tell me what each wire color controls what on each of the connectors I believe the new ignition came from a 96 or 96 Ls400. Any help would greatly be appreciated. Yeah I looked everywhere for the key how frustrating.
