View source for Toyota Paseo GT 1.5 odometer Starlet P9 mod

= Modification Overview =
Modding guide on how to make the '''Toyota Paseo 1.5 GT''' (5E-FE 1995-1999) odometer plug and play "oem-clean" for the '''Toyota P9''' (EP91 4E-FE 1996-1999).<br>
This mod has the focus on not messing with the car wiring by depinning and changing the OEM wiring, but by modifying the GT cluster.<br> After all while GT parts are relatively abundant, GT cars themselves are far less common on the road, making these odometers extremely cheap and readily available in the Japanese used-parts market. 

There are three connectors on the back of these odometer clusters the connectors are both the same type however the pinout is different.
Most left connector is named '''A''', the middle one '''C''' and the most right one '''B'''. So: '''A, C, B.'''

== Instrument Cluster Wiring Modification ==
These are the modifications needed to be made on the GT cluster.
Below you will see the tables of traces that will need to be cut first. After cutting them we will rewire them.

=== Cutting Traces ===

== ODO Correction ==
If you want to correct yours to avoid getting in trouble by road inspection service. You will have to change it back to your old ODO meter milage.<br>
Please do not abuse this trick.. I have set mine from around 110.000 to 300.000. Just so I don't get in trouble.<br>
In the image below you can see how I did it.

</gallery>

== Notes on the Modification ==
Leave the four lamps open (remove bulb). Do this for: '''open door warning, SRS airbag warning, park warning lights''' in the bottom left corner under connector A. Also next to connector A you have a the indicator light and a '''triangle warning light'''. Leave the triangle warning light open too. All these light are unused and '''not connected''', connecting them might short something not reverse engineered.
They must all be left OPEN FLOATING ('''important''').
