How To Wire Electric Fuel Pump Relay Bypass Rewire Hard In this video, i show how a fuel pump relay works and how to bypass yours. i also show how to rewire your fuel pump for an upgraded fuel system or race car. The relay should have 4 pins on it. they are usually labeled 30, 85, 86, and 87. steps: 1. wire pin 85 of the relay to the 12v supply wire from the stock ecu that you just cut. this 12v wire will now energize the relay to turn on. so now instead of the stock ecu energizing the fuel pump, it will energize this relay. 2.
How To Wire Fuel Pump Relay Jul 1, 2019. #3. thanks for the diagram. a few notes to clarify how to wire, along with some questions. wiring plan notes. 1. black wire from fuel pump to ground. 2. purple yellow from fuel pump to a solenoid. 3. wire from solenoid to the terminal on battery, with a fuse. Then, run a jumper wire from the negative terminal of your battery to a ground point on your vehicle. this will complete the circuit and allow power to flow directly to the fuel pump. to run the fuel pump directly to your battery. this will ensure that the pump gets the power to function properly. This video details how to add an electric fuel pump to your project. we focus on making this modification along with a classic update kit, but the process wo. The relay actuation side of the circuit needs only a small amount of current, so you can use a low amp switch and small gauge wire (even on long runs) to hook it up to the relay. for the electric.
How To Direct Wire A Fuel Pump 2 Part Guide This video details how to add an electric fuel pump to your project. we focus on making this modification along with a classic update kit, but the process wo. The relay actuation side of the circuit needs only a small amount of current, so you can use a low amp switch and small gauge wire (even on long runs) to hook it up to the relay. for the electric. Here’s a summary of your 3 options: method 1 (one wire relay bypass) – easiest, quickest, and safest. it requires only a small piece of wire, and you don’t need to touch the fuel pump. method 2 (all the way) – best avoided. method 3 (part of the way like method 1) – an alternative option if method 1 is not possible. Procedures. disconnect the negative terminal of the battery!! look for the fuel sending unit inspection service cover at the back of the trunk on the right side. pretty easy to find. take that cover out pretty easy to do. a newbie can do it!!.
