My question is simple, I need to put a 1400 Ohm resistor for my door locks can I use a 1500 ohm. Same goes for the unlock function I need a 426 Ohm can I use a 470 ohm, and if not can some one give a hand on what to do. Thanks a lot newbie on this.

Usually 5 to 10% of Value
Local Electronics Shop should be able to mix & match or use a Variable Resistor

if you use 3 of the 470 ohm resistors you should get 1410 ohms that will be ok and be within your tolerance level. as far as the 426 your out of gas you need to go to Radioshack or a place like that and find the values or do what i do and use potentiometers. best thing invented for dodges/chryslers

You can just test them when you're in there. take scrap piece of wire and twist resistor on. touch ground and door lock wire through resistor and it will either work or it won't. then after it works not running, start the car and test again. sometimes voltage change will affect function if resistor value is close to max/min tolerance. it will not hurt to try any combo of resistors, worst case it just won't work.....to answer your question thru my experience, yes those values will work.

I usually would go to Radio Shack or a electronics store and buy the value pack of resistors.There is usually 100-200 different resistors and only costs a few dollars there will your resistors in that package.You will have lots more for other jobs in the future.

you can put the resistors in series orparralel to reduce or increase the resistance value, try this

If you take 7 1400 ohm resistors and wire them all in parallel you'll have 200 ohms. Now, take another 7 1400 ohm resistors and wire them in parallel for another 200 ohm load. Then, wire these two separate groups together in series and you'll have 400 ohms. Should be close enough. :) ------------- Kevin Pierson

for $1.50 you can also buy a vriable potentiometer- much easier- and you can "dial-in" your resistance.............from Radio Shack
