Sure, but you must run all associated fuel system parts as well.

It is either the headlight switch,or the dimmer switch.

What the devil is a 20r ! if you mean you have an older normally aspirated engine and you wish to fire it....spray some neat fuel directly into carb with the filter off....this should at very least turn it over so it draws fuel for normal delivery to jets in carb !! DO NOT PUT A LOT OF FUEL DIRECTLY INTO THE CARB....BE CAUTIOUS.

run to autozone and buy the Haynes repair manual if they have it its in the back

replace gray flasher relays under driver side dash, should say "Flasher" right on them, they may be either round or square.

If you have a 22r carbed then all 22r carbed engines from 1981-1995 will interchange. You may need to use sensor out of your old engine however. The 20r,22r,22re,22ret all have the same mounts and tranny bolt patterns. how ever there are lot of differences. you can swap from a 22r to a 22re but you must also swap the entire vehical wiring harness to do it right. if you have a 3.0L i would keep the same engine. some people have swap to the tacoma 3.6L but that is a expensive swap not exsactly bolt on so to say. If you have a 22re then stay with the 1986-1987 22re because the newer 22re use different computers, electronics ,sensors and more.. Same story with the 22ret. I hoped this helped.
