Dodge SRT-4, HOM toys option, and WI injector placement

[Richard L]

I think I can quite confident that you can wire the set up as you mentioned - except for the red and black wire for the following reason.

The #21 and #22 from the DDS3 juction box is only limited to 1A of current. In case your priming pump is drawing more than 1A, it will affect the DDS3's power supplying stability to the rest of the components and devices.

Please wire the Red to a healthy switched +12V with a wire gauge about 12-14awg (also place a 5A inline fuse for safety) capable of carrying 8-10amps. The black wire to any chassis ground.

The rest will be connected as follows:

- Yellow to Priming pump red.
- Grey to pressure switch (806-162) grey side.

I will redraw the wiring diagram in the morning to include the custom made pulse extender box.
