This is a mod that has been talked about for years on here and I figured I’d give a rundown of what I did and changed when I converted my ’98 SRX 700 over to ’00 SRX electronics. If your mechanically minded at all this swap is quite doable by most anybody with basic hand tools, the only thing you will need to borrow or buy is a flywheel puller. I will put the list of parts down first and then do my best to describe why I did what I did.

Most parts are a matter of swapping the old for the new ones but there will be a little bit of altering of a couple of things here and there.

The wiring harness is easiest changed with the engine out, which will make  changing the stator easier. The headlight wiring harness is an easy swap, unplug the old one and feed the new one in and plug the connectors together.

FLYWHEEL NOTE

*If you plan to use the flywheel from the 00 and up you will need to do some fab work by measuring and have a piece of aluminum welded onto the mount boss for the pickup coil. The new flywheel is smaller in diameter which means the pickup coil needs to be moved from the stock location. OR you can use a flywheel from an SX-R  with the dual bulb electronics (01 and up), it’ll bolt right on with no mods needed. I got this tip from Betheviper.

If you want to you could also use a set of cases from a Viper or 00-02 SRX, they have the pickup coil boss in the correct location for the smaller flywheel, then it's a matter of switching all the engine components over.

The carbs are a direct swap just put whatever jetting in you want, I went with 01 SRX jetting across the board it seems to be the safest and most popular jetting to run.

The dash panel is a matter of screws to swap it then just put your gauges in the new one. Your tach will need one wire changed to allow it to work with the new electronics, the backlight bulb power wire. Flip the tach on it’s face and you’ll notice the blue wire powering the bulb, this needs to be cut and fed to one of the posts with a brown wire on the tach. All I did was cut the blue bulb wire off, crimp a hoop onto that wire, locate a connection with a brown wire, there's a few and it doesn't matter which you use they all go to the same source. Use a screw driver to take the screw out and then screw the blue bulb wire onto that terminal with the brown wire.

The coils need to be wired to the connector so they will plug into the wiring harness .

The mounting bracket for the regulator bolts in place of the old bracket with 3 or 4 bolts and it goes just above the left footwell. This bracket has the tabs to secure the relays and condensers to.

If your doing this to a 99 SRX then this step is unnecessary but if you have a 98 then you need to make up an extension for your powervalve servo. The new wiring harness places the connector above the regulator like the 99 and up SRX. What I did was peel back the wiring on my old harness where the servo wires were to give me enough to splice into the new harness. You could always use pieces of wire rather than cut up your old wiring harness. I cut the connectors off the new wiring harness and soldered in the wires I cut off my old harness and run the wiring along the air box to plug into the servo.

You could skip this step by buying a set of longer pv cables and then your servo would mount up where the 99 and up ones do BUT you will have to fab up a bracket and weld or bolt it in place to mount the servo to. Either way you do it you'll have to do some work.
