A quick and dirty way would be to put the XFi harness completely alongside of the CRX harness, and hack it up at the base near the plugs...or I could take the time to strip all non-engine wires from the CRX harness and leave the accessory wires (lights, wipers) intact. Any suggestions about how to most efficiently add the engine bits to the CRX while still allowing the accessories to work? I don't really know what to expect from the fuel pump/gauge either. I'm not even thinking about climate control yet.
Here are some things I found out:
-The Metro radiator is taller than the CRX bracket, but can't be forced in because the front crossmember is in the way - The CRX's radiator will be needed, but its hose hookups are inconveniently placed on the wrong side of the engine bay...perhaps some additional hose and some elbows?
-The CRX's shifter is a few inches father away from the engine bay than it is in the metro. I may have to do something a little crazy to get the shifter to work.
-Exhaust looks like it's going to be just fine. It does indeed have an o2 sensor on the manifold.
-The Metro's gauge cluster is a 3 gauge - no tachometer.
-The CRX's subframe in the engine bay is pretty well 3' on the dot apart, the metro 2'10.5" - luckily not the other way around.
-NYS still isn't done mystically changing the title from PA to NY yet <bites fingernails>. Guess we'll see what happens next week!

Use the Metro engine harness and the rest of the wiring from the CRX. It's up to you if you want to remove the CRX engine wiring. I would, just because I don't like "extra" parts. I installed the Suzuki Swift TBI in a carbureted Tercel. It's almost like Suzuki made the system universal. Not too many connections outside of the engine harness required to make the engine run.
If you're using the CRX gauge cluster, the fuel gauge will work like Honda intended. And the sending units have almost exactly the same resistance, so you could use the Metro gauges if you wanted to. And the CRX fuel pump should work fine with the Suzuki TBI. The pressure regulator is in the throttle body, so the pressure should still be correct. But I'd check it with a gauge anyway.
Climate control should be easy unless you want A/C. Use all the CRX stuff and just connect the CRX heater core to the engine's heater hose connections.
I'd be tempted to find a radiator that fits better.
The shifter shouldn't be too hard, they both have basically the same setup. Nothing a little welding won't fix.
