Digikey

a) +5VDC Voltage Regulator (P/N LM7805CT-ND, $0.65)

b) 100K-ohm Micro Trimmer Potentiometer (P/N 987-1060-ND, $2.02)

c) DPDT Micro Relay 12VDC (P/N Z768-ND, $3.00)
http://search.digikey.com/scripts/Dk...l&name=Z771-ND

Notes:
- I picked components that are higher in spec, especially operating temperature range.
- The DPDT relay handles dual O2 sensor applications, but it's so cheap you could just not use the second pole for single sensor applications (e.g. 4-cyl).
- Although Digikey's mail order prices are much lower than Radio Shack's store prices, you may run into minimum order and service charge adders, an then there's shipping cost.

I think you're better off to pick up a project box and breadboard at RS.

Radio Shack

1 - Project Box 3x2x1 (#270-1801 $2.49)

Also you can use resistors instead or pots but I like the pots incase you get a car that need a voltage tweak to get the computer happy.
Yeah, not me either!
