- Jacobs FC1000 ignition amplifier install writeup for the 2nd gen Mazda RX7 FC3S.

The 2nd Gen RX7’s already have a great ignition system. We are going to make it even better!

Cost: ~$140 Summit.com, Jegs.com, etc.
Advantages: More torque in the low rpm range - especially on ported engines, better fuel economy.

Ok now. After that wonderful fireman discussion, let’s look at what we got:

Now, out of the box we have got a thick red and black wire, and 4 skinny wires: white and black, red and green. The other wires we won’t be using, so tuck them up out of the way somewhere.

Lets mount the box. I chose the ultra-ghetto self-tapping screw method. A pure favorite among DIY's (Do It Yourselfers)...

And there we go! All mounted in place!

Lets start wiring it in. Since the fuses aren’t plugged in yet, the unit doesn’t have power, so I’ll hook up the battery wires first. Red goes here (+), black goes here (-)…
*HOWEVER, disconnect your battery first! We don't want you to do an OOPS!.

Here’s the stock coil and igniter.

Clip and strip the wires like so:

and pinch on some spade terminals.

Plug in your red and green wires…Don’t forget to heat shrink them to prevent cross arcing.

Heat Shrinking... DO A GOOD JOB!!! =)

By now, we have the power supply, and the igniter going into the FC1000. It's time to send the fc1000 to the coil. Note how the (+) and (-) is molded into the coil.
