There's this website www.reliable-store.com
They have books on ALL vehicles.
it covers wiring diagrams, electrical diagrams,
fuse diagram, torque specs, PCV, error codes, fault codes, service info, repair info, parts info, troubleshooting owner's/service/repair/parts/maintenance manuals etc everything totally..
I have 1987 toyota 4runner model and I keep servicing and when needed repair it on my own. worth it !!!

there is an amp located in the back rear drivers side, check that, and there are fuses near battery , a radio fuse and also an amp fuse, i change my battery every 3 years as a prevention so I don't get stuck.

most likely it will fit unless the manufacturer changed the application that year but its not likely suoldnt be a problem

could be starter relay in fuse box under hood

Buy a thermostat, a thermostat gasket, and some blue sealant (RTV) from any auto parts store. On the driver side of the engine, there is a radiator hose that connects to the engine just under the wires for the spark plugs. There are two bolts. Remove the bolts and pull off the hose. Some coolant will leak. Remove the old thermostat and gasket. Note how the thermostat is oriented so you can replace the same way. Put the gasket and thermostat back using some of the sealant and then re install the bolts. Total cost is around 15-20 dollars. Feel good that you saved a few hundred bucks and only takes about 20-30 minutes.

thing is you only need to swap the senors on those engines not the computer

if it jump over the stop peg you half to take the cover off the speedo and move it back with your finger

the cluster needs to be calibrated to the pcm before the speedo and tach will work. You will have to take it to the dealer to have it done. The last time I had to do it, it cost me 70 dollars.
