remote start 12 v power wire

some cars dont use 12v high amp so you have to go to the battery for the remote starter power, in some cases some cars use only 10amp 12 v for the power wire in this case can i remove the original fuses from the remote starter and use one 5amp just to get a little lower of the original of the car?

It really depends on the draw of the system you are installing. However, with the DEI systems I use, I do exactly what you are asking. I remove the included 30 amp fuses and replace them with what the vehicle's ignition wires are rated at. Because the DEI systems I use do not have a separate fuse for parking light input I use negative parking lights to ensure the system draw is minimal.Installer, IT support, and FFL. I need less hobbies.

As long as it is enough to control the ignition of the car. I never go under the hood for power tho. If i can't get it from the switch i may use power from the BCM...Mike M2

And to add to Mike's comment, if in doubt go to the battery other wise a good candidate is usually the main constant (from battery) power supply to the fuse box.
