Napa Auto parts will have them AutoZone and Advanced Auto Parts may also carry them.
If you do not have cat converters you can do without them: here's how...
TAB & TAD solenoid valve eliminators – eliminate codes 81 & 82.
You will still get 44 & 94 codes because the computer looks for a change in the amount of oxygen by checking the O2 sensors when the solenoids are actuated. Actuating the solenoids provides more oxygen in the exhaust, changing the O2 sensor output. No change and you get the 44 & 94 codes.
Don’t do this if you have a catalytic converter H pipe. The catalytic converters must have the air from the smog pump or they will eventually clog up and choke.
Pay a visit to your local Radio Shack to get some heat shrink and some crimp on tap terminals. They do not stock the resistors. Or you can use the Ford connector pin kit from AutoZone.
18 gauge crimp on taps Catalog #: 64-3053
Put the resistor inside the heat shrink tubing and crimp the connectors on. I would choose the Ford pin connectors since they should plug in the TAB & TAD wiring. That way you haven't modified the wiring so it is easy to re-install the TAB & TAD solenoids if emissions testing comes to your area.
Two flat pin connectors.
One 82 ohm, 3 watt resistor.
One piece 3/8" heat sink tubing 2" long.
Two pieces 3/16" heat shrink tubing 1 1/2" long.
Solder the pins onto the resistor leads using electrical solder.
Slide the 3/8" heat shrink tubing over the resistor.
Slide the two pieces of 3/16" heat shrink tubing over the two wires, leaving the flat part of the pins uncovered.
It helps to have the resistor leads straight and not bent as shown in the first picture when you apply heat to the heat shrink tubing. That way, the tubing shrinks more evenly.
Finally, apply heat to shrink all the tubing uniformly.
Bend the leads to fit the spacing on the female TAB & TAD connector sockets.
Push the connector pins of the completed resistor assembly into the empty female TAD or TAD connector sockets on the wiring harness. The resistor assemblies replace the missing solenoids: one resistor assembly per solenoid socket.
Do not crimp on the pins and wrap the mess with electrical tape and say you got the idea from me. If you do, and I hear of it, I will say unkind things about your intelligence and family heritage. Do Quality Work!

yeah i have cats so i need them, i grounded them with the ignition on and the tab clicks but the tad doesnt so i assume its toast, also have power to each one also thxs
go to junkyard and look for older lincoln/mercurys with 5.0s, might not have to have a 5.0 but I found they for sure have them and they work good. also look for older F-150s they have them as well. I just did this, cheap and work perfect.
