ECU Terminal Diagram 4A-GE 20V Black Head (1996-2000) 1997 Toyota AE111 Corolla Levin 4A-GE 20V MAP Sensor, Black Head 20V From Toyota 4A-GE Engine Repair Manual, South African Edition Click each image for a larger sample Part # for 20V Black-head ECU 89661-1A360, 1A470, 1E090 (5 Speed manual compatible) 89661-1A470, 1A480, 1A490, and 1E100 (4 Speed AT compatible, OK for 5 Speed as well) 89661-1A660 (6 speed manual compatible) All have the same pin outputs except for AT specific outputs on AT models that can be ignored for MT applications. 1EXXX part numbers are from the last year models which have cleaner fuel maps and slightly leaner mixtures for less response and more detailed diagnostic output... (not suggested for swap applications as it is trickier to operate correctly. 1AXXX ECU's are basically similar except for equipment differences in auxilary outputs depending on if the car came with TEMS controllers, ABS, and other things that are not usually used on swap jobs anyway...and does nothing to the engine operation if disconnected at those pin locations... (more accessible recommended for black-head applications) 1A660 is for the 6 speed equipped AE111 which are compatible with 5 speeds as well but mated with 6 Speed transmission outputs, it has premature rev cut points in 1 st and 6th gear and slightly changed timing curves for a split second after lift throttle and reapplication to ease and protect the 6 speed's synchro and reduce driveline lash. All of the above ECU # are for the AE11X black-head 20V 4A-GE and operate on vacuum sensor (MAP). ![]()

quick question as i've got my car in bits atm wiring up a vvt light. all i need is to connect the negative side of the led to the vvt. is it the middle block, bottom left wire which is labelled vvt on the above diagram? thanks. p.s dumb question i know but hey, i have an IQ of 0 edit: yes it is btw. easy mod..... fookin great mod!! VVT light FTW!! Edited by JDM, Oct 12 2009, 04:39 PM.

Probably late for JDM's application but here is the web page I used when I wired in an led. Be careful, use the correct resistor as you only want a max of 20mA flowing through the led circuit. Put a heat sink on the transistor too or face the very real possibility of frying it. http://www.my-acoustic.com/Car/ECU/20vMAP_problem/20vMAP_problem.htm I fried mine messing with this and ended up replacing my transistor with an NTE 2382 which will handle 9.2 amps. The lettering on the transistor will face the main connectors. Use some silicone to glue the heat sink to the board to keep it from vibrating and breaking one of the legs on the transistor. Been there done that. Hope this helps. |
