Run a seperate switch and relay. Run power from the battery (fused, preferably) to a relay, and from the relay to the fans (splice into the existing wiring). Actuate the relay from a switch inside the car. Easy enough.
Why in the world would you want to do this?

The PCM turns the fans on around 220F, and back off at around 200F. The dinger/alarm comes on around 225F. Running the fans all the time is just going to do what the PCM should be doing. If the fans are turning off when the temp alarm is still going, something's not right, like a faulty temp sensor or faulty fan relay.
The most involved part of a head gasket job is taking off all the extra stuff before finally pulling the head... and putting it all back on... You don't need any sealants really. You'll want to check the head for flatness (overheating a lot can warp the head...). If you have a FSM or Haynes manual, it should walk you through it pretty well, and be sure to follow the torque sequencing steps. Buy/borrow a torque wrench if you don't have one already... Stuff clean rags in the intake/exhaust ports and the cylinders as soon as you open it up. If you have power tools, the job will go much faster, but you can get it all done by yourself with hand tools in 8-10 hours, assuming you don't need to have the head milled. Use ziploc baggies for bolts, and label them... Label the wires you disconnect as well. The extra 2-3 minutes doing this will save you 30 minutes of frustration as you direct curse words towards an inanimate object, such as your car... When you put the timing belt back on, rotate the crank a couple of turns to make sure the timing marks still line up. Skipping one tooth is easy. If you haven't seen Jeff's SOHC timing belt how-to on a 1st gen, take a look at it - www.boogerracing.com somewhere...
