1991 toyota land cruiser hdj81 japan spec

Looking for a diagram for a 1991 Toyota Land Cruiser Hdj81 Japan Spec Diesel 80 Series

The Japanese version will be identical to US/Canadian as regards Alarm-R/S and Audio. Dead easy to do. You will need indicators rather than lights, GREEN/ black and GREEN/ YELLOW, POS with steering column loom. 12V+, ACC, Ign. 1 and 2 and starter all in ignition switch loom (test). Lock and unlock, low current NEG, in white plugs in driver kick panel. Door triggers and possibly hatch, wire that goes NEG at domelight when a door is opened possibly RED / white, or red with silver dots, also to be found in driver side (assuming right hand drive) floor loom at kick panel. Tach either at rear of tach gauge if one is present, or use a DEI 454T induction tach generator. You will need to fit a hood pin switch but you won't need a by-pass. Headlights and horn, both NEG trigger in steering column loom. Sorry I can't be more precise but I haven't worked on one of these since about 94!

US petrol (gasoline) version is now in the Downloads/Manuals section search as "91 Toyota Land Cruiser". The wiring should be the same.

Hi guys I have got some questions I would like answered. My Truck is a 1991 Toyota Land Cruiser Diesel Japan Spec 80 Series I have found this wire diagram in the vehicle section the wiring should be the same as the 1991-1997 US Spec as my diesel has power windows and electronic door locks and Automatic Trans. https://www.the12volt.com/installbay/alarmdetail/2096.html I am sure most of the wiring is the same I will find out more when I have the dash apart and I can access the wires. The main differences are - Diesel - Wait-to-start to diesel glow plug light. It is also known that the Tachometer is low voltage less than 3v? when I find the wire I will verify. I need to know what relays and diodes will I require or if I can attach to a factory relay on the H2 Harness, 24-pin connector? Do I need Diodes for door locks and door triggers? and does the Brain have any built in relays? Does this mean that every (-)200mA accessory will need to be connected to a external relay or factory relay? I am also not quite sure where to hook up the wires below and what there function is for? H2/1  PINK/WHITE      (-) 200mA IGNITION/FLEX RELAY CONTROL OUTPUT H2/7  BLACK / YELLOW      (-) 200mA DOME LIGHT SUPERVISION OUTPUT H2/9  DARK BLUE      (-) 200mA STATUS OUTPUT H2/10  PINK              (-) 200mA IGNITION 1 OUTPUT H2/18  VIOLET / YELLOW      (-) 200mA STARTER OUTPUT any help would be great thanks :)

Thanks howie II this helps out a lot seems like all i need to find is the tach wire and glow plug wire. I also have more questions specific to the Viper 5904 alarm and I have posted here. https://www.the12volt.com/installbay/forum_posts.asp~TID~130584~PN~1

Well, I told you one place with an external option for the tach wire, Directechs mentions another, the check connector adjacent to the battery. Glow plug wire will be at the gauges or when you program the 5904 you set it up for diesel and you have a built in starter delay.

In answer to your other post there's a built in relay for starter cut/anti grind and I believe one for 2nd. ignition. The only diode you will need will be a 1N4004 on the unlock side look at the info I posted before. Remember to power up ALL the constants, red x 2, RED / white and RED / black. You will have no problem with tach voltage and hardwire the tach and program it as such, voltage settings just won't work on a diesel especially at your latitude.

I am currently building a list of wire colors making a cheet sheet of all the wires I need to hook up to my truck and reading thru the 5904 manual from dei it states that it is not compatible with the 508D Field Disturbance Sensor... "Note: Sensor ports 1 and 2 cannot support sensor 508D due to current limitations. These ports are also constant power and ground connections." I have the 508D module and was wondering if it is still possible to hook it up to the 5904 and if so where do I hook it up??

I'm wondering the same thing! Unless they are asking you to hardwire it to H2/19 trunk trigger via diode separation. Might be worth a call to DEI from your end, I can't call toll free to the US.

it states "current limitation" if its only current limitation I should be able to get by using power and ground from the chassis..
