TOYOTA STARLET EP8 Wiring connections, Connector IDs & Loom Layouts Rev. Last Updated October 0 Author & Copyright : Alan Mears Location : Perth, Western Australia Contact Email : alan@mearcat.com.au Online Forums User Name : Mearcat This document details a large amount of wiring information which I could ascertain from the two main wiring looms (Cabin & Engine Bay) that was provided with a 99 (en ) EP8 Toyota Starlet T (E-FTE) front cut, however much of the wiring layout and information will be appropriate to later Toyota Starlet models (with eg slightly different connectors or wiring colours). Please note that there are no specific details of wiring connections and connectors in the doors, nor rear wiring loom of the car - due to those parts of the car not included with the front cut. The front cut was a Manual Transmission E-FTE which was not fitted with TEMS or ABS, so no specific details of those components could be provided. To advise of any corrections, please contact me on the above email address.
