You only have to add two 14 or 16 gauge wires to your existing harness from under the rear seat to the top of the fuel tank.
Add one connector under the rear seat to the current connector and one wire grounded/bolted to the body. The other two tank end wires are added to the connector at the tank module.
The standard 2.8 APEX male and female pins can be ordered individually from Mouser Electronics. Only takes about 30 minutes work to add the proper ends and and add them to the current harness. I used 14 gauge wire when I did mine. Cost to add two wires to the existing harness with the required terminal ends was less than $25 for everything.
You may even be able to source the APEX wire ends locally in your country?
