1uzfe - Are SC400 and LS400 engine harnesses Sep 30, 2009In my case the SC400 sub harness on the engine had a two pin connector for the coil and a six pin for the LH cam sensor, crank sensor, and hydraulic fan pump solenoid. The LS400 harness will have a 4 pin connector where the 6 pin connector is on the SC400 if memory serves me correctly.92 sc400 swap wiring with factory ecu | Lexus-Toyota V8Jun 10, 20191UZ wiring harness. | Lexus-Toyota V8 UZFE ForumsJun 08, 2011Engine Swap Wiring Conversions by Phoenix Tuning | LexusSep 07, 2007See more results Lexus SC400 Stereo Wiring Harness - AutoZone Order Lexus SC400 Stereo Wiring Harness online today.
