3SGTE Coil On Plug Conversion Project GT-Four

In this video I install the components required for a coil on plug conversion. This is for my Gen 2 3SGTE for my Gen 5 Celica GT-Four ST185. I use 1ZZT coils which fit perfectly and a custom bracket and harness. The wiring for the 1ZZT coils as you look at the coil pack are Pin1: Earth, Pin2: Trigger, Pin3: Ignition feedback, Pin4: Power. I used 7.5amp 18 AWG wire for the harness. The coils are second hand so I am unsure what car the came out of. The spark plugs are NGK iridium BKR6EIX. All the plugs are new. Music by Bensound.com
