YouÕll be swapping connectors back and forth, so it might not hurt to capture both sides of the connectors if possible.. If you are in a situation where you are disassembling this yourself, I'd carefully label each wire as you go along. I doubt you'd ever persuade a shop to do this but it'd help. Later, you'll be poring over the CQ and 200 electrical schematics, and the more you can identify manually in advance, the easier the job will be. You also need the left side engine harness. It runs from the fuse box to the compressor, and I think goes forward up to the headlight assembly. You'll need parts of it for the A/C wiring. Take the heavy cable lead from the starter to the jumper post. Take the underhood fuse box with all fuses and relays. You will use the CQ coil (identical) but why not take it anyway? DonÕt forget the altitude sensor, which is under the rear seat. Get the battery wiring including the heavy cable if you're going to re-locate your battery to under the rear seat. Is your relationship with the dismantler really going well? Ask him to cut out the battery box, you may be able to adapt it. If I had to do it again, I'd take the interior climate control panel (and wiring), and the small computer display inside the dash. This display shows boost instead of one of the CQ functions, (avg. MPG?) although only displays up to 15 lbs, and you're going much higher than that, eventually, aren't you? Learn-from-our-mistakes tip: swapping connectors in order to mate the 200 harness to the CQ hardware is time consuming. It took many hours and a full bottle of Stabilant 22. Anywhere you can also take the assembly, like the climate control head unit, would be a plus: Easier to just swap the unit than change the connectors.
