Anyone really good on Tiger wiring?

The ignition switch works and the light beside it lights when on. The headlights, turn signals, brake lights, etc all work.

I have no wipers, blower or dash lights. Do these all get power from the same place? Both fuses are good and power is on both sides of fuse block.

I wanted to check the wipers to see if there was power, but there are black plastic connector looking things attached to green on one side and fabric covered wires on wiper motor. But they don't seem to separate and I didn't want to break something.

Where should I start looking first to fix this?

With patience! The dash lights grounds are all daisy-chained together. Be sure all of those grounds are making contact on the back of the respective gauges. The power going to the dash lights comes off the main light switch. That switch must be on for the dash lights to work. Check the spade connectors on the back of the light switch.
Wipers: again, check the connections at back of switch. Those wires you see with fabric covering may indeed be brittle. Mine had been reconnected by the PO with newer bullet connectors... see if you can somehow check for power at those connections or at the wiper motor itself. Always check your grounds. I may be wrong, but I think the wiper motor has power going to it all the time and the switch grounds the circuit. I'll need to drink beer to remember. :D
Check the blower motor the same way: be sure grounds are good, check switch connections, then power to motor.
Good luck
 
Hi PITT40,
the instrument lights are fed via the main light switch to a panel light switch,three postion, off,bright,dim.
You may not have the switch on or working,sometimes contact cleaner will help to clean the corrosion from the contacts inside the switches.
The wiper motor,as Drbill has noted,has ignition controlled power,fed via a green from the fuse box,only live with ignition on.
White wire from ignition switch to fuse box controls those circuits,but you have brake lights so power will be there.
The wiper motor needs an earth return to work,this was via a single black wire to the back of the Rev counter,a better earth is to take it to the dashboard padded roll 1/4" unf set screw under the corner mtg.
The blower motor is likewise earthed via a ring terminal fixing the blower assembley to the car.
