Hello,
I am needing resistors in the range of 700ohm to 900ohm and unfortunately, Radioshack has no resistors between 860ohm and 1K ohm.
Where can resistors be bought (locally?) in the range of 700ohm - 900ohm ?
Or will I have to use several resistors in series?
thanks

Try Farnell for bulk or in series.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

I do not know of any national companies that can help you. There are still some electronic parts retailers left. I have no idea where you are located, but you may try to look in the yellow pages for an electronics parts retailer in your area.

The common size resistors don't have much between 680 and 1,000 ohms. You could try a 5k potentiometer to find the correct resistance value. Then use standard resistors in series and/or parallel to obtain the correct value. Here is a calculator to use 2 ( or more ) resistors in parallel to obtain a desired resistance: https://www.1728.com/resistrs.htm
A good source for electronic components is JameCo Electronics. https://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDisplay?langId=-1&storeId=10001&catalogId=10001
Good luck! ------------- Soldering is fun!

There are two electronic suppliers within 20 minutes of my house that sell resistors in many, many sizes. I agree with above, grab a phone book or do some interest research for a local electronics supply house.
Digikey.com or mouser.com are two great online resources for resistors.

I'd question WHY you need such specific values.....
There are E24 groupings for 1% etc resistors instead of the normal 5% E12 values (10, 12, 15, .... 68, 82).
But normally such values are done with series or parallel combinations - 2 E12 resistors will usually get you within 1% of your target resistance. (Choosing between a parallel or series combination depends on desired failure mode, PCB space etc.)
