So you've got a Mitisubishi 3000GT or a Dodge Stealth, and you want to switch from the OEM low-impedence injectors to aftermarket high-impedence injectors (like Injector Dynamics). You have to disconnect the OEM resistor pack, but now the injector wiring won't work. What to do?
First, get one of these: 8-way connector
Wire it up like you see here: http://farnorthracing.com/stealth/ID_injectors.html
And puchase this back cap. The connector slides inside and prevents the wiring from rubbing on something and shorting out. It has a pair of mounting holes so you can bolt it down to the original resistor pack backplate. Slick!
