Ecumaster forum

Hi i have a 2000 lexus gs300 and i have pretty fair wiring capabilites but never done anything this advanced.. i have already wired a safc neo into this car and found out that it is almost impossible to find 2 of the same ecu pinout diagrams for this ecu that coincide. So that makes it a challange already lol. But can you please tell me what 2.maps switch. 3. 4,5 ,8 ,10 ,13-20 would go to lol?? As in either what pinout im looking for or what the sign is on the wiring diagram.. and also which diagram you are referring to . Because of the afcneo install . I know all the rest of the pins lol.. o yeh. And what do i hook the silicone tube coming off of the unit to? Im guessing a vacuum line. But does it need to be somewhere specific .as in right off my intake .etc?.

Please try to work on your punctuation, it's hard to figure out what you need help with when all the words a strung together.

First off, the vacuum nipple goes to the intake manifold, any port is fine, so long as it's after the throttle body.

MAP Switch is only used if you have two maps. So it's not needed.

PINS 3-5 go to your crank trigger. However, I don't know which one, considering your motor has the crank sensor, and also the cam sensor. But I'd assume the crank signal is all that is needed.

8 is a pull up, meaning that if the signal on something is weak, then you tee this wire in, and it helps amplify the signal

10 is freq in, this is generally used for AFM's which you don't have.

13-16 are your analog in,
