Let's get your project wired 💪

Back in 2015 I wanted to fit a standalone ECU to my 1998 Glanza V and at the time there were only a handful of Starlet owners who had fitted one.

The two main Starlet tuning specialists were at least a 5 hour drive away and it meant months without my car, which was my daily.

I wondered if it was possible to just order a wiring loom from one of these companies and fit it myself and have the car tuned locally 🤔

It was possible to order a K20 swap standalone engine loom for a EG Civic so I knew it must be possible to do this for a Starlet too.

I was told it wasn't possible and I was quoted £2200-2500 for a DTAFast S40 ECU, crank trigger, new (OEM bodged) wiring loom and mapping. That was over 10 years ago and we offer a brand new, better than factory spec wiring loom, without mapping, for just over £1500 bundled with the Link ECU G4X Atom!

Which injectors are coils are you using in your build?

We stock all of the most common options. Shown here, left to right is Standard Denso (Sumitomo TS 090), TE Junior Power Timer for injectors, followed by K20 and R35 GTR coil pack connectors.

Unlike a lot of the aftermarket wiring industry (especially in the UK) we only use genuine connectors supplied by our friends at Corsa Technic , not cheap copies made from inferior materials.

2X EP91 G4X Monsoon plugin wiring looms 💪

There are 3 common ways to fit a standalone ECU to your Toyota Starlet.

1. Cut the original ECU plugs off and crimp on new pins for the new connector
2. Use a patch harness
3. Have a brand new wiring loom made for the car

Our preference is always option 3 since the original wiring is now over 30 years old.

Did you know that Toyota revised the engine wiring 4 times for the EP91?

That means each different model Glanza V manual, Glanza S auto, etc... all had 4 different engine looms!

People commonly assume there is only 96 spec and 98 spec due to the facelift but it's not as simple as that.

The first revision was around April 1997, the second was in Jan 1998 and the last was in 1999. For the purposes of fitting an EP Wiring engine loom for a standalone ECU, the last 2 wiring harnesses are interchangeable but the same cannot be said for the rest

is our favourite brand of ECU, for a good reason, they are rock solid 👌

Unfortunately we can't say the same about some other brands at the same or cheaper price points.

We've been using Link products since 2016 when we ran the G4+ Atom in our own Glanza V, we then upgraded to the G4+ Fury then G4X Fury!

Our wiring looms use Motorsport grade Spec 44 wire, TechFlex Insultherm fibreglass braid and all genuine connectors ✅

We only use the best crimp tools and every terminal is crimped to manufacturer specifications, unlike many other automotive wiring companies.
